SpaceX plans to do in-orbit refueling for its BFR, though. I may be oversimplifying, but it seems to me this is a fairly similar feat than cross-feeding. Couldn't the experience gained in this help for that?

During launch, you need the receiving tanks to be at 50-100 PSI for the rocket to work, which probably means the fuel being pumped at a pressure that is much higher.
