Ability to remove last assigned User Access Administrator in a subscription
When subscriptions are created, they inherit a User Access Administrator from Root. If we add a User or Group to the User Access Administrator role to the Subscription, we are no longer able to remove it after even though it could be redundant due to inheritance from the group above. We have to assign a new permission to be able to remove a previous assignment. From my understanding this is so that we do not lose access to the subscription. I believe this behavior should only exist at the Root level because a Subscription will always inherit permissions from those levels.
