I can think of two occasions where a GDC ruling underwent a lot of tweaking or a reversal, Dave. "In" the loading zone in 2005 (can't remember if touching was originally a requirement, but it sure became one by the end of build) is one. The other was in 2002 with tape measures. Admittedly I wasn't around that year, so I don't know all of what went on, but from what I have heard from those who were around, it was "No tape measures to contact the home zone" and then became "You can use tape measures to contact the home zone".

This year, there has only been that one conflicting Q&A set, and a bunch of clarification on electromagnets vs solenoid actuators which was apparently unclear to some people for a while but is now quite clear.

Regardless of what reversals there may/may not have been in Q&A, the rule stands: Don't modify the motors, except as specifically allowed.
