There are often a couple of barriers to this.

Firstly, you can’t break what is already there, so any evolution of the general platform often has to make wider guarantees than a single framework.

Adopting ideas from any single framework too quickly may put you in a worse position. A framework can evolve and choose when to break compatibility, a language or platform standard has a tougher job in that regard.

Some things that front end frameworks have settled on are now being looked at for standardisation, but I’m personally still wary about changing something like the ecmascript for. It would be an easier call if there were a standard library which simply needed an implementation, but we aren’t quite there yet.
