            ### 2) Admin users are *not* superior to #channel.ops, and don't
            ###    have God-like powers over channels.
            ### 3) We assume that Admin users are two things: non-malicious and
            ###    and greedy for power.  So they'll try to elevate their
            ###    privilege to owner, but they won't try to crash the bot for
            ###    no reason.

            # users can only give out capabilities they have themselves (which
