I disagree! This is definately not a kernel related issue. If you want to let
users create groups, make a setuid root binary that will edit /etc/group
accordingly. I don't think the kernel *ever* accesses /etc/passwd or /etc/group.
The kernel is just responsible for making sure that the process which is run as
user/group is confined to that access.
