No, it makes more sense for semi-admins to be able to
act against
admins. Admins are better equiped to handle "hostile" acts, and should
have enough experience to handle semi-admins who do something wrong.[0]
We cannot expect that from new users, and it is they who must be
protected against less well thought out actions of inexperienced admins.
But admins shouldn't need actions taken against them except it extreme
circumstances. In extreme circumstances we would want full admins
handling it, because they are more experienced. It is the routine
stuff (and actions against regular users are generally routine) that
can be done by semi-admins.
