> mostly web developers who care about this in the first place.
I’m not sure what you mean by this. We care about our users and how they use our websites. JavaScript is everywhere and has been the de facto frontend standard for the past few years. Supporting no-JS is starting to feel like supporting a new browser. As much as I’d like to, from a business and product point of view, the numbers are just too small for us to even consider it.
I didn't imply that all web developers care about it, but that most of the people who care about it are web developers. I won't deny that it's still a minority.
