My take is that frameworks matter less the more it is just agents, emitting code. The frameworks were just tools supposedly making the job easier. We have much better tools now.
Take web environment. It matters a little to your large coding buddies, whether they emit React or vanilla JS. For this particular instance, the learning set was pretty much similar, consisting of both React version of given app, and vanilla version (or even C/C++ version, since going thru wasm is a viable approach). It is possible that some core concepts (such as virtual DOM or redux-like store) are less likely to disappear, but the chances are that there is just no sound need for React-like framework in already pretty mature vanilla JS world.
Somewhat of a sidenote, take reverse engineering. It is a common thing nowadays to have your favorite closed source library / app "disassembled" and put together "anew". Any frameworks used for creation of the original app are irrelevant.
