Totally. When I make Oculus friends, I hate that I have to tell them to find me as [my husband's username] because he signed up on the device first, so now I can never have my own Oculus account.
I solved the Beatsaber highscores problem by being really really good at Beatsaber, so I only play on Expert+ and he only plays the lower levels. That way our high scores are separate. :)
