I'm pretty sure krampi and Klaus are of same species as Wortox and also travel via soulhopping, so theoretically he can put survivor in krampus sack similarily how they were trying to steal beef in a short.
Sure bonded beefalo will teleport after you, but first you have to get off wait get back on so this would be a welcoming quality of life change, secondly and more importantly you will be able to use it in combat in order to dodge, because as of now you basically can't use souls while mounted - you can heal yourself but you don't take damage, and you can't soulhop.
