So this means that, in theory, a team can't have differing bumper configurations? Say that sometimes they want to use a full 100% enclosing set, and another time a minimal 67% set?

I don't dispute the GDC's right to call this 2 robots vs. one, and I don't think Ken and the rest of team 1519 dispute it either. But I don't think the GDC should have accused them of attempting to lawyer the rules, when there is no clear rule defining what a ROBOT is. As I pointed out above, this is a completely valid interpretation following FLL rules, where the ROBOT is specifically defined as the NXT/RCX "brain" plus anything attached to it. In the absence of a FRC definition, 1519's interpretation of the ROBOT being the required parts - RC, Rockwell, Fuse block, etc - plus various attachments (which in their case includes frames, motors and wheels) is reasonably valid.

Perhaps a ruling should have been requested of the GDC during build season, but any team submitting a Q&A takes the risk that other teams will copy their designs, and 1519 took the alternative risk that their unique design would be allowed. They were not prohibited from playing because of the ruling, they were just restricted in their game play. That's the risk they willingly took.
