personally I don't see a need for the module, but anyway.
It's questionable as to if stacking 12 modes violates RFC1459, section 4.2.3.1 Channel Modes states that when using o and b you can only stack 3, but at the end of the same paragraph it states any combination of o and .... so it's up to interpritation as to what the meaning is. So does it mean using o and b together or is it using o or b anywhere in the stack.
ChanServ being a client applies to this module as any other client would, thus covered by RFC1459 in this case.
