Basically, to make sure RoleCount is adjusted to include the new node, and we also need to scale up with:
parameter_defaults:
  <RoleName>RemovalPolicies: []
  <RoleName>RemovalPoliciesMode: update

And re-run deploy by replacing template above with:
parameter_defaults:
  <RoleName>RemovalPoliciesMode: append
Comment 2 David Vallee Delisle 2022-01-26 16:25:59 UTC 
A valid point was raised at our compute triage meeting is that we don't use the terms black/white list anymore. We need to use deny/allow list.
