This was observed scaling from 2 to 1.

What should happen: The 2nd replica is deleted. The first one is not touched.

Observed on v0.14.0

I think what happens is updating replicas (with no other changes) causes the diff algo to detect changes in the pods. So it's doing an update on the pods (which is a destroy/re-create). This is surprising. Changing the replicas shouldn't impact pod updates.
