Transfer tanks, not fuel. In-orbit servicing using robots, please. or just dock the tanks as vehicles.
Sounds like a good idea. The problem is that for weight efficiency reasons in modern rockets the tank is the rocket. (So much so that they often crumble if you are not providing sufficient internal pressure.)
I'd accept a future in which weight efficiency is slightly reduced to enable in-orbit refueling with standardized tank delivery. As others have noted, it seems extremely challenging without it.
