And if you are running a 4s or 12-14 cell setup, you can choose a motor with a higher wind so you aren't pulling too much current. If a motor was pulling 100A at an even 15v, that's 1,500 watts! I highly doubt anyone here is drawing that much power continuously! A 10Ah battery would only last 6 minutes if that were the case.

And the Quark rates their ESC at 125A continuous, and it uses the same FETs and same number of them. So, there's no reason why the MM can't (other than maybe PCB trace limitations).

Castle's statement is to cover their butt. They know people are going to push the spec'd limits so they apparently incorporate a bit of derating with this in mind.

And about the BEC: IMO, until all ESC makers incorporate switching BECs in their ESCs, they should design a very simple circuit that automatically disables the internal BEC if it sees over 9v.
