I think we need more thought around how to derive a store from a previous store. Currently, overriding certain building blocks won't work as expected.

Isn't it already mutable without the type annotation?

I think buildingBlocks should be frozen.

Yes, it should be frozen. I'm only talking about the typing. Doesn't this work?
const buildingBlocks = [
...INTERNAL_getBuildingBlocksRev1(prevStore),
];

Since updating Do you know if this fixes that issue? It might somehow relate to my project using a custom store or it could be something else. I've not been able to work out what's happening yet. |

Summary
If a previous createStore has already overridden createStore, we should try our best to compose with it.
