Alan is correct. The GDC did clarify that,
here,
here, and
here.
The
inspection checklist (Rev F, line item 30) doesn't included a specific reference to allowable fastening systems, and first mention of bumpers in the inspection
reference materials (Rev D, page 4) don't cover fastening systems, either. The reference materials do summarize several important Q&A responses (pages 10 thru 15) including those that deal with bumper mounting (items 50, 60, 71, and 79 of the Q&A summary).
So even though Alan is right, it is not hard to see why some inspectors might have missed this point. Inspection standards are higher at the Championship, so teams whose robots passed inspection at a regional despite having a non-conforming bumper fastening system should anticipate being required to correct that when they get to Atlanta.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
