Someone should design a wiring connector that is oriented tangentially to the axis, with one part attached to the hub, the other to the fork, so forward rotation on the wheel effectively pushes the parts together. This would make for an easy removal of the wheel....
There is the Schmidt SON SL hub and fork dropout that doesn't require any connectors at all.... well, at least not any connectors in the usual sense.

It does require specific dropouts to be used, but is otherwise not too difficult to incorporate into the bike.
