"simply dispense with the connector altogether and solder the wires in place"
If I took my car to be serviced and my mechanic said that to me I would not be very happy, and that's just on a motor car, top speed 140mph. I would not like to be one of the poor astronauts who have to hope the solder will hold when traveling at 17,321mph (approx).
Why not go the whole hog and just use a bit of gaffer tape?
