I hate webdevs, I hate browser devs and I'll have an autistic meltdown in this thread! More news at

Gotta agree with the first paragraph.

Lads, how viable would you say it would be to make a booru-like board without js?

You should call them documents or more specifically HTML documents instead of web pages.

Because we have to make shekels and brainwash goyim to the point where the west will simply cease to exist. Come on it's 2018 (almost) be open-minded you fucking anti-semite. The true internet 2.0 is here and you have to accept it.

I see that question the other way around: Why the fuck would you need js for a simple image gallery?

It's right there, in css:
content:url('i.imgur.com/PghEJhe.gif');

nice blog post
didn't read lol kys

Agreed, but useless people have to make money somehow, it's not like we should put them is gaswagen or something, right? Think of the children. While cities remove advertisements from buildings and shields, web gobbles it down. Think, in future we'll have absolutely sterile grey looking architecture overlapped by your AR system's content provider ads and textures.
What else should be interactive? Downloadable exes? APP for this, APP for that? Web is a perfect solution for short-lived server interaction.
It's an easiest way of giving you an identity after you log in.
Modern JavaScript libraries are in fact what Java, Flash and Silverlight used to be. Forced down corporate standards.
That's what Gopher is ideal for. Why don't you fuck off to Gopher instead, huh?
Webpages create a seamless experience, once they used to be works of art. Browser devs can't be responsible for whatever your proprietary shitty player normie installed on his computer bugs. Once there used to be "internet suites" with browser, instant messenger (IRC/XMPP or proprietary), RSS reader and email client bundled together. Nowadays people use browser for everything and a dedicated IM issued by their social "network" developers.
But in Firefox and forks it is easily configurable. Disable autodisplay, pipe everything to programs, use yourube-dl binder for youtube-like sites that obscure third-party downloads.

You have a built-in wget in your os already, I assume.
Some browser have and it leads to more privacy concerns and easier profiling of users instead.
It tells you the hostname. IP is usually irrelevant when everything today is behind the "cloud" to protect from ddoses.
You have to connect to some sort of server and then fetch your IP from it. It's a privacy concern, aside from Tor browser, it tells you IPs of all three nodes you are connected to including exit as it appears to be "your" IP for the webpage you visit.
This is what an OS should do. If you don't have full control over OS, maybe you shouldn't change your browser settings too.
In fact, you can. Right click - inspect element, delete the line from rendered page code. Easy as that.
Hats and weird themes on imageboards are usually delivered through custom CSS. If you don't already override it with your own preferred style, well pity on you.

Because it feels like you can't do anything beyond an old static Web 1.0 page without the damned thing. I just checked a random booru, and it had no less than 16 first party scripts. And my goal with a new booru would be precisely to add more features, so God knows how much of js' functionality in boorus could be replaced by... whatever else that isn't a script.

Firefox has. Chrome has. What other browsers do you need? I assume, more obscure browsers have this ability too.
User agent is isrrlelevant if you think it's some sort of big bad way of tracking you. Today's tracking techniques use javascript to profile your hardware, which is hard to spoof, and they completely ignore UA unless it says search robot or something.
It's a legacy item from times when your father used to pick up on his classmate chicks. Back in the day not all broswer had same features and web devs explicitly had to state whether their website is compatible with certain browser or not, vice versa for browsers. Gecko for Netscape, IE for Internet explorer, and so on. You visit an IE-optimized website with Netscape. Bad for you, the page is all fucked up and unreadable. Today all browsers simply include all possible combinations like "Mozilla, Gecko" for backwards compatibility with old websites, and that's it. Another fraction is to assume what OS you are using to deliver you a download page for Windows of for Linux, and overall statistics comparison for something like:
OMG! 2% of Linux visitors are reported by technology-oriented website, year of the Linux Desktop has come!
This is corporate fault, namely Microsoft's and Netcape's. They pushed different walled gardens back in 90's.

What else should be built-in? Video player shouldn't, but your "assburger_functionname" should. Nice doublethink there. Go fork yourself a new browser with cool useful features you like.
This is why people use stable distribution with old features when they don't waht to change to everything new right away. This is why ESR exists, nigger.
It's called browser console. Same as on your OS, "normie UI" and "full control terminal". Press F12.

Good luck on offloading tag database searches on your server. Hope, you have money for those double-cpu Power9 servers.
