. Now, if the solder mask and paste mask are 1:1 scale we must have special notes on the fabrication and assembly drawings with instructions for mask adjustments or otherwise we won't get what we want

don’t know about PCB assembly facilities (for recommendations on the solder paste layer). But I guess they are making the necessary adjustments for reliable results just like the board manufacturers do with the solder mask layer
