The Microsoft Open Maps team did add a lot of road surfaces based on machine learning a little while back. A lot of that was just adding surface=paved on roads where most people would have assumed by default it was paved, but still useful to have it explicitly set regardless. Though you'd need to check the edit history, find where the surface was added and see if the user was part of the Microsoft Open Maps team to know where it came from.
