If a group has a few admins and they argue with each other, there is a risk that some of them will delete group in anger.
A lot of contents, which have been created by other people, maybe vanish instant. This option should be limited for just website admin.
They will be wary that data may be lost too easy.
however, the group creator can, which is still something we don't want. Plus, group creator is unable to leave group, or be removed as group admin (even by himself). I think since we've added this into the pool of improvements, it would be great if we fix these as well
