You're thinking of <G24>, the pinning rule, not <G22> the robot contact rule.

There was no specific exception for ramming robots on the ramp.

I'm glad that we didn't have to change this because the open space in the back of our bumper didn't really affect contact outside of the bumper zone. I hope that next year angled cuts are allowed, too, because it doesn't really change game play if they are disallowed.
Going from what I can tell from the picture, such angled cuts are the ones that are currently disallowed (source) but should be permitted.
With regard to the bumper cuts, let me back up Billfred's assessment of the situation. <R35> specified that bumpers must be designed per the figure drawn; Q&As were issued for clarification of just how stringently that had to be followed. They stated: "The only cuts allowed in bumpers are vertical cuts, completely through the bumper, and perpendicular to the plywood. Bumpers may have gaps as shown in Figure 5-1 in <R35>." (from here), and reiterated this position quite clearly on several occasions.

You won't believe how many teams had issues with this. FIRST should have definitely made this stipulation in an update, and not just in a Q&A, but the teams have to realize that they're responsible for following <R35> in the first place—all the Q&A did was suggest how much leeway they ought to have at inspection, in terms of minor deviations from the rule. In this case, it was absolutely clear: vertical cuts only (i.e. beveled ends to clear the floor when climbing the ramp, horizontal cutouts to clear the crest of the ramp, etc. were illegal).

I have many more bumper horror stories to tell...maybe I'll get to listing them later.
