I guess it depends heavily on the airport. But gate staff usually say “have your ID and boarding card ready”, but then its just that I scan the boarding card myself anyway. I usually do not check in luggage, if that is what you mean, and if I do, there are automatic dropoffs in a lot of places, and those that are serviced by staff just checks boarding card. Security gates only check boarding card. During covid lockdowns, some required that you upload your ID for online check-in, but I have not seen that since.
