I think HTML is considered too challenging or 'low level' in modern front end development. Components are created with material UI, or bootstrap. No one seems to be doing it by hand.

I like coding html (and css) by hand. I find it easier to do that than to deal with frameworks and tooling. So I read articles like this and often find something new (TIL about fieldset). But I've yet to see anyone else do this professionally.

So I don't think most people will ever care about this stuff, in the face of modern "best practices". It's just going to be nested div soup, from here on out.
