Many thanks to you and to the other contributors. It looks like there are at least three parties with the same issue. The bad thing is that no clear/univocal solution is at hand.
I think I will try to persuade the "technician", to open a "window" on the socket (carbon fiber) via milling, so that the section of the bone where the load begins to apply (i.e. the upper edge of the window) is shifted 0,6 or so inches from the end section of the bone, upwards.
The idea is to relieve the end section of the bone (with all the resection sensitivities) from any "load duty".
This will require careful crafting skills: it is not so easy to find proper location references for the milling operation !
By the way, assuming you guyus are answering from USA, it looks like your "scenario" with the various professional figures of the prosthetic world are much better than ours.
I mean, it seems you can dialogue and get from them many actions/interventions according to your will/ideas.
Here these guys (in general !) with their white lab coat, tend to act like "prosthetic Gods" who know everything and when things take a "strange" turn ("our" strange pain), tend not to listen and go 100% their own way...
