Well, I considered to leave the nutted axle and came to the conclusion that I was not trusting it to be secured.
You lenghtened it by pulling and twisting of a few degrees at the extended lenght.
The outer sleeve has 2 flats to allow it to be hold while tightening the external nut but such a little twisting movement is enough to unlock it.
Mmm... no!
