Yeah, mixed feelings from me too. I guess before we do that, can we ask what commands people want to use? I'd rather it not be used a short circuit for stuff that could be fixed in MM or implemented fairly easily for a device. That's my only reservation, that having it may reduce the incentive to fix/enhance MM itself.
