The problem I think is the inversion of control — django owns your code; you’re just a citizen within its confines. You’re typically hooking into the framework’s runtime, and thus everything you do is mediated by the framework — great when you’re doing what the framework wants you to do, and a massive PITA when you stray from the golden path.
Not to mention it bifurcates the library ecosystem — you end up with a react forms library versus an angular forms library versus a vue forms library that are all fundamentally the same yet somehow split, by nature of the framework they hook into.
