Auto Groups could be enhanced by a feature to model "Union Groups" as well. A Union Group contains all users which are member of at least one of the configurable Member Groups.
E.g., Union Group U may be configured to contain all users from all its Member Groups A, B and C. Users which are in at least one of A, B and C are also members of the Union Group.
In addition, Override Groups could be useful there as well, i.e., if group O is configured as Override Group and a user is member of both A and O, he will not be member of U as well.
