Mine is that the useState hook is an actual plague on the entire React ecosystem. Regardless of your opinions of React, if you wanna use something then use it right.
I don't like working with them any more than you do, but they're necessary to enforce read/write-level security. Without them, there'd be no differentiation between reading a variable and writing variable from an external class, which kinda defeats the point.
From a development standpoint, they're an extra hurdle to clear. From a security standpoint, they're a necessary evil.
