> 'useSyncExternalStore()' -- Gack!

> Now...that "little" it's-not-a-framework-it's-a-library whose scope is supposed to be confined to just the "view" part of MVC (by which I mean: "React") is inserting it's tentacles [...] into the _model_.

useSyncExternalStore doesn't care about what you do in your model. it's for connecting your view to your model in a way that doesn't give you inconsistent states when concurrent-rendering-funkiness happens.

you could even say that useSyncExternalStore exists because React maintainers want people to be able to use whatever state-manager they want (instead of useState/useReducer/whatever) -- uSES was necessary to enable that in 18.
