This all seems sensible to me, but I've got some burrowed worry about how this actually works, when we'd have some separate RegistryProvider. I guess it might rely on some registry clone behavior like considered in #7453, which would re-assign the registry for the selectors / controls in the process of undergoing the clone?

@aduth That's a good point, I thought about it and yes it's challenging if we map the selectors and controls inside the store creation funciton. It means the clone function needs to reassign the selectors/controls somehow while if done at the registry level It would be generic, easily clonable but at the same time a little bit less performant.

I think this should be reconsidered as part of the "clone" implementation and whether the performance gain in long posts is important enough to be worth the added complexity.
