Filed an issue to represent work started here:
#20273
#20696

The proposal was to scale the underlying RCs with non-zero replicas proportionally in order to mitigate risk.

Otherwise, scaling up currently increases the size of the newRC and scaling down could decrease the sizes of the old ones, both of which would have the effect of hastening the rollout progress, which could produce a higher proportion of unavailable replicas in the event of a problem with the rolled out template.
