I just going to post something similar, however need a way to delete users from the users from an environment whether they exist or not. However especially if they are still active users. We setup environments based on the BU or team, and an org or team change can result in user moving to a team/BU who is not allowed access to the environment. Therefore, we need to have a way to completely remove users from any non-default environment for any desired reason. It is senseless that we have to go through every role they might have and remove it, to somewhat remove their access using an essentially rigged up work-around method, rather than proper enterprise-level support functionality.
