did a basic validation (suggested in the issue) by spinning off 4 instances in
2 different envs running 4.20, one with this change and other without. Both
were configured with userdispersing vm allocation algo.

End result is same for both envs, each host has 10 instances running.
Transition from Initialize -> Starting -> Running is small for a lean image.
