I don't think it's possible for a framework to do all of the following: add functionality, preserve existing functionality, and reduce the possibility of dubious implementations. Also, I do think packages like those from tanstack have made it easier to implement react well. From what I can tell, most people's bad experiences with react come from applications which incorrectly use redux or similar global state as a cache for data from the server. The new Redux Toolkit Query and similar Tanstack Query approaches to handling server state are much more manageable, and in conjunction with appropriately using URLSearchParams you can often get away with no/minimal global state. In other words, React is not the problem.
