US used to be like that too. When polarized plugs first became a thing, they wouldn’t fit into older non-polarized outlets. It took decades for all those to be replaced and I’m sure they’re still out there. Somewhere
Still I have one (1) in a stairwell in my house. So far I’ve left it alone, partially because it also has a stupid piece of stair molding blocking part of its cover plate but mostly because I have never in all my years found any reason to plug anything in there.
Somebody probably originally intended it to be for a vacuum cleaner or something, but even the corded ones I’ve owned have had cords more than long enough to reach both ends of the stairs from a selection of other nearby, non-stupid outlets.
I live in a country with two plug types and actually have to use a fuckload of converters
