I'm just speaking from my own experience where we had an redux app with 30-40 reducers operating on quite a lot (100-200) of dynamic attributes in those objects and approximately the same amount of attributes that are initialized just once and don't change over the lifespan. I can't imagine using a single context for it all. We used thunks heavily, of course. I would prefer to look at the code to better understand how we approached problem solving in each case. Also, have you ever had to invest a good chunk of time to solve performance issues in any of those projects? We did.
