I'd wager there's enough people, but I never looked into it so I have no data other than the people I know IRL.

I will add something though, I don't think the other way lends itself too well to being "discoverable". I just had my brother copy some data across documents with different formatting and he didn't know that "paste without formatting" was ever an option and now I think, if it ever worked the other way around, would I ever know that "Paste with formatting" is an option if the app defaults to unformatted paste?
