So far in January, I have left my Kippie Bag in my carry-on without any repercussions at all, not even a comment, at the following airports (in order): KWI, EWR, YYZ, MCO, ORD, TPA. This seems to be a complete non-issue now that TSA staff are focusing so much attention on IDs. I can't use my old INSPASS any more, even though it's a government-issued photo ID; the drones are unfamiliar with it and freeze up totally. I've switched to my passport.
