The instrrument is a full Boehm. This model has an articulated C#/G#. The hole for this note is on the tenon, so the hole goes through the socket on the top joint and through the tenon on the lower joint. The hole, incidentally, is in the correct position and all models really should have it there, but makers take a cheaper option and normally put put lower down on the bottom joint on normal Boehm models.

I think makers differ to the problem inherent in having the tenon hole, that is, there is only ONE spot to have the horn together. Some of us pull out at the middle and this would misalign the tone hole(s). Also a subtle change in the lateral alignment to adjust the one-on-one Bb would be rendered impossible.........so, let's just not put the C#/G# there unless you do a uni-body horn like Rossi.

....not to mention further weakening of the tenon.

That's why the the tenon and the sockets are (usually) metal-lined.

Not to mention also that the regular position of this hole on two piece clarinets doesn't really have much of a problem. The only problem, a little stuffiness in the C#, sounds much worse to the player than to anyone listening.

Any such adjustment is a bandaid to some mal-adjustment.
Indeed, I believe that if that linkage is designed well (which is rare), then the mating surfaces are both tangents to the body at their line of contact, so that a slight rotation of teh lower body with respect to the upper, makes no difference to the linkage.
I often modify these linkages to make this so.
The biggest problem I have with such tenons is finding a piece of tenon cork of sufficiently high quality to have no flaws near the very narrow areas of cork. Also, it takes a lot longer to shape such a tenon cork well, around that hole.

I have yet to run into a clarinet where the linkage is NOT affected by the alignment.
I also find a subtle corrective measure better than being subject to the vagaries of compressed cork and earning "frequent flyer miles" with the local repairman.
