I have some backstory on this question and it's really VERY upsetting and a counter example of the idea of gracious professionalism as a whole.

Let's not use Q&A as a weapon guys.

Now, as a counter to this point, if the hook and loop is confined to areas that would be...

A) Fully contained within the area of the bumper where "hard parts" are allowed as shown in figure 4-7 below R21-G.

and

B) Could be covered with the aluminum angle specifically permitted within R21-E

Also, per R21-D there are accommodations within the rules specifically to allow reversible bumpers.

Personally, I'm ignoring this for now as I agree that it mostly concerns areas where interface occurs between robots in the course of a match. We've done reversible bumpers since 2010 (except for last year of course).
