Description

Currently, placement rules can be defined based on user names or (primary/secondary) group names as a direct mapping. This promotes creating much more pools than might be needed, and leads to administrative overhead when changing names or adding a new user/group.

It would be good to have a more elaborate mapping, e.g. translate user/group names into pools (including potentially mapping multiple users/groups to the same pool), either manually or via regular expressions.
