I've noticed all the core groups include the "All Users" group in them.
Others, which may not be core, but still pretty much "official", like "Static Page Admin", don't.

So as a rule of thumb, should a group include "All Users"?
After all, even without including it, every user will still be in this group no matter what!

For example, if I hacked "Mail Admin" and unchecked "All Users", mail admins would still be a part of "All Users" because "All Users" itself includes them.

So should we include them and if not, how come the core groups do?
