Is FRC giving high CG robots a free pass on defense?

Videos like this upset me a bit, especially when I think back to a robot I saw in 2013 that was like 16" wide x 44" long x 50" tall (or something silly like that) that would tip over CONSTANTLY with even the slightest nudge.
Back then, no one ever called fouls on robots that tipped it (and half the time they tipped themselves anyways) because it was obvious that it was the fault of the team for building a tip-prone robot. I wonder had that robot been built this year how many teams defending (or just brushing by it in passing) would have been red or yellow carded.

IMO, FIRST aught to make teams bear some responsibility for making sure their robots can withstand the rigors of NORMAL match play, including being defended via normal bumper-to-bumper contact. Like it or not, it's part of the game.
