Q: From my understanding this is intended for lunar only. Is there a 
plan to propagate this to other series?
Just thinking out loud, it would be nice to get rid of one derivative 
(even though I would have to find others to crank;)), but given that it 
is a derivative that people may already use, it may break that, so I am 
curious about the strategy here.
