seems really odd to always call importChange, pruneChanges, etc.. with this IsDescendantOf function. I think it makes more sense to make orderedPendingChanges a struct with a field of type isDescendantOfFunc. That way you include it as state for the type orderedPendingChanges.

I don't think keeping the function as a field in the orderedPendingChanges is good as we will keep this reference in memory until we garbage collect, but passing it as an argument then once the function returns the argument will be dropped, and the orderedPendingChanges is a linear struct which means there are no recursive calls

I don't think there's much more overhead keeping a single reference to s.blockState.IsDescendantOf in a struct that includes an attribute for []pendingChange. The question you should ask yourself is, is the type orderedPendingChanges intended to be stateful. I would argue yes, since it requires a subset of functions of blockState. You could just add it to a constructor for orderedPendingChanges when it's called in NewGrandpaState.

Maybe have this newer mockgen command using the format described in https://engineering-handbook.onrender.com/development/tech-stack/go#mock-generation ?

That way there would be less diffs in the future once we migrate fully to having all mockgen mocks in mocks_test.go.

Agree with you but we can do this in another PR since it is out of scope for this PR
