Whatever removes React is the way to go, it's the most poorly thought of library out there.
I don't know about that. But when it comes to ecosystem of components, nothing beside Vue, beats React. I spent weeks looking for a good Select components with custom item rendering, async options loadings. Writing a component like that from scratch takes a lot of time to get it properly. Yes, there are Vanilla components like Tom-Select, but then you have a soup of different components with different interfaces and it becomes a mess to make them talk to each other reactively.
I wanted to use SolidJS for its performances, but it has a poor ecosystem. I tried to ditch front-end frameworks all together and I ended up synching states between components manually. In the end, I guess React (or Vue) gives you a good balance between pro and cons.
I guess, ecosystem is important beside mere performance. This is not only true for fast shipping, but for developer experience too.
