Normally they mean they are using React Context, useReducer and React.memo/useMemo.

Most of the people saying that are using that are suggesting it lowers the code complexity as in the code is easier to understand or follow.

They probably will also split up the application state in multiple React context, one for auth, one for settings, things that aren't depending on one another.

Especially, when you are application doesn't have to manage that much state yet. I think it's a reasonable approach to get started with it. You can always switch to something like Mobx state trees or Redux at later time.
