I think we have a generation of developers that only know React and they're so engrained with it they simply cannot imagine a world without it. If you really can't find a use case for web components then you're living in a bubble.
Now we are seeing the exact same thing again. People only know React, so they want the standards to look like the only one thing they know. That doesn't make it a good idea. Every time this comes up we exchange simplicity and performance for easiness and temporary emotional comfort. Its only a temporary win until the next generational trend comes along.
There's a very tiny use-case for web components. And even there it's riddled with a huge amount of potential (and actual) footguns that "in the bubble" devs have been talking about for a decade at this point, and some which were finally acknowledged: https://w3c.github.io/webcomponents-cg/2022.html (no updates since)
That's weird, we've been using them at my company for a number of years and there's plenty of other examples of them being adopted elsewhere too. This continues to read as, "it's not React, so it's bad."
