I know react is moving towards SSR quite a lot but I don't think hydration or SSR are actually common for react devs to care about. You also have very similar issues with hotwire, so I'm not sure it makes React more complicated.

For all its flaws, React is still extremely "small" as far as front end and server side front end goes.

That might change with the increased push towards next.js and SSR though.

Very true. For every day dev, all the framework bits are stuff the average dev doesn't need to know at all. Ie, none of the devs at my company know anything about that, and that's just fine. We get a ton of work done.
