I think the main risk for this kind of framework is that you spend as much time ironing out these kinds of "edge cases" (debounce, transition states, error states, transactions, authorization, url bar state, scroll bar position, paging, efficient re-renders, etc. etc.), which in practice are crucial to most non-trivial software, as you would have just writing the usual boilerplate and retaining fine-grained control.

It's great that people are innovating and creating new abstractions, and I'm sure there are apps where the tradeoff is worth it (internal CRUD-focused enterprise stuff comes to mind), but my knee-jerk reaction for a large app is that it will make easy things easier and hard things much harder.
