Can we use a StyleDiff somewhere instead? Imagine an animation of background-color triggering region rebuilds every frame :(

Not sure yet if it is worth additional complexity, in most cases (at least when touch-action is not involved) region building should be very cheap due to ability to bail out early in the common case. We'll see if it actually shows up in profiles.
