I like to travel light. I only have six keys I carry. I think that's on the low side. I've seen people with ten or more--who didn't have janitorial duties.
So it's still there. But maybe the statute of limitations has run out.
PS I can't remember the last time I went to a hotel and got an old-fashioned key. In this brave new world, is it time to give them up? That would be great. Keys as we've had them are clunky and inconvenient.
