It's somewhat amazing how the JS ecosystem is still struggling so hard to do things that, e.g., Laravel solved years ago. It's as if nobody ever heard of server-side rendering before.
Yes, it genuinely is a mess where people are continually reinventing the same things again and again on a loop and no two projects are the same, almost none of them are by the very nature of being React particularly well aligned with web platform standards and have major parts of their ecosystem captured by weird VC companies who don’t have the same priorities as your developers let alone your organisation.
That’s not particularly true for say Angular or jQuery or Web Components etc.
