There is a significant penalty paid for the inconvenience of lugging around that wheeled thing.
I also made the same observation (less GS and others) when standing in Group 1 - this is mainly at PHL, which has a pretty decent number of GS on the flights I am on. I also used this data to bolster my argument that it is BG3 and up that really abuse the bin. Others denoted it was the Group 1 flyers.
This is a vote to BG3 instead. I also echo the OP's notes that F folks, though some do carry-on, do so a lot less - and because they are separate from Y, don't really cause bin problems.
