Well, the shutter already has contacts for flash triggering. In case these are adjusted for x-synchronisation one only would need to lead the wiring outside or install a PC-socket.

But, this would mean a modification to the camera not everybody tolerates, and furthermore loss of working of the bulb socket.

And in case one has several models of this type of camera, the modification of one of those old Flashbar-socket adapters seems even more appropriate.
