That doesn't really affect your main point, but @Najawin, we actually have valid stories depicting other River/Tennant adventures, chiefly the Day of the Doctor novelisation. And of course there's her various appearances in Big Finish (starting with The Diary of River Song) where she goes back on the Doctor's timeline and has adventures with a bunch of Classic Doctors, only to wipe their memories of her once she's done.
