I am a developer, I can guess what site needs JS, like payment sites, sites that are actually SPAs. Check all submissions from HN and let me know how many have forms , load fine without JS and don't complain that JS is off and then fail on submit?

It is easy because I don't get popups for cookies, for allowing location access, no fancy scroll effects , I also disabled animated GIFs.

If you are a webdev and you don't work on an SPA but for some reason you site is half broken with JS off then use the standards and put a message that informs the user that JS is required.

I would not setup this to some random person computer, ad blockers too can screw with shopping carts and some websites also beg to stop the ad blocker , so I would not install ad blockers too any random person either, but here on HN JS off by default is a good advice, most should understand that if page is blank or some button does nothing then it might be a JS related issue.
