"Fwiiw: I cut off 2.5" from my wife's hip belt strap once. That was in the middle of nowhere, on a very long trip, and I used the webbing for a crucial repair on something else. Saved the trip."

There isn't much to be saved and it will hurt the resale. That and you may need the feature in the future. I did major surgery on a pack once and decided it was better Ti buy what I wanted and sell the offender. That rewards and supports the manufacturer that does it right, insuring future UL products.
Cut the handle off your toothbrush and bask in the warm light of symbolic weight reduction. I have my titanuim potty trowel, so I know I'm ultralight :)
