This is part of why I believe that smart hybridization is the key. In a complex application, you need qualities from all major schools of UI framework design, but broadly speaking we’ve been obsessed with trying to find a “silver bullet” one true paradigm that fits every use case, when no such thing exists.

I also think that UI frameworks try to hard too be “magic” and unopinionated where they should instead be highly communicative and naturally guide developers into the happy path. So following your example of the excessively re-rendered button, the framework should really be detecting the unneeded redraws and complaining to the dev about them and potentially even presenting as compiler errors in production builds until they’re fixed (which the compiler offers hints on how to do).
