The thing about shoes is just dumb anyway - I don't know if there was some period of time where it was required elsewhere around the world but I never experienced it. Literally the only times I've ever had to take off my shoes were during the two times I've visited the US (vs. a over a dozen trips to European and Asian countries).

Liquid restrictions were also lifted in my country four or so years ago for domestic travel, so it's still annoying when getting ready for an international trip and I remember I still have to do that...
