Bear in mind, I've been dealing with bumper rules since '06. Some things are obvious to me because I've been dealing with 'em so long, but that particular definition/description has been in there since at least '08, if not '06. (I can't quite remember whether "bumper zone" or "frame perimeter" came into play first, or if they came in at the same time.) The key thing about the bumpers is that they serve 3 purposes: Protect the robot against impact with other robots/field elements, Identify the team by number, and Identify the alliance by color. If you've got a suggestion for the GDC that will result in looser bumper rules, while still fulfilling these three purposes, I suggest that you let them know. With all the restriction-easing going on, they might welcome the suggestion as one less place the inspectors have to inspect.

You've misunderstood what I'm talking about regarding the string. This string is a fixed part of the robot, not the visual aid. The string used to identify and measure the Frame Perimeter is different and irrelevant. By your suitable example this would be more of a belt for your pants than a measuring tape for the fitting of said pants.
I'd suggest removing the need for specific supports for the bumper (basically removing R26) by opting for a rule more similar to the safety of robot mechanisms, like G3.

G3
ROBOTS whose operation or design is unsafe are not permitted.
Violation: FOUL & DISABLED. If the issue is due to design: Re-Inspection.

Or, modified for bumpers:
Quote:
G20
ROBOTS must be in compliance with Section 4.6: BUMPER Rules throughout the MATCH.
Violation: DISABLED. If the issue is due to design: Re-Inspection.

We're already doing the first half by disabling failed bumpers. All we need to do is implement the second half (teams need to prove the problem is solved to re-enter match play) if we want to allow more restriction-easing.
