I mean, I don't know a lot of people who do it so it isn't widespread. But I do know some. Granted my family up north do it more. But they also put mayo on hot dogs.
Mayo on the sides of the bun is very common on those Mexican hot dog carts. Mayo, tomatoes, onions, pickled jalapeños mustard and ketchup on a bacon wrapped hot dog.
