The "api userID" for facebook/twitter/etc. is numeric because it's always been numeric (and facebook explicitly doesn't guarantee anything about their lengths IIRC); that doesn't imply anything about what their real pkey is, just that it was numeric back in 2003. It's pretty easy to transform a UUID back and forth into a number.

I've used UUID-as-pkey and had it work well.
