I can't even begin to count the number of codebases I've seen where developers rolled with this idea and ended up with royal spaghetti. Everyone thinks they can build these frameworks from scratch, but they overlook the unknown unknowns. Nearly every custom implementation of state management, complex forms, async flow management, etc I've seen in the wild is riddled with countless bugs that could've been avoided if they just picked a boring and widely used library. And I've seen plenty, because I'm usually the guy that gets called up when no one else can untangle it anymore.
Yes, I have seen that countless times too. Developers that have no idea how to write original software think they can go without a framework and then write a framework. That is stupid, and its because those developers know something about frameworks but never learned to program. Stop toying with irrelevant nonsense and actually release a product for users that solves from some real business requirement, which is certainly not a framework.
