No problem. Cut that section out is fairly easy. I already made a top layer for the 7BIT layout. I just don't want to make a separate batch of 7BIT top layers. Cutting and sanding the regular top layer would ruin it. You can make it work, but without lasercutting it, your cut edge would be all rough, and you risk cracking it.
Whereas lasercutting doesn't have that effect. In fact laser-cut edge is shiny and smooth, called. Otherwise you would have to do flaming polishing on the cut edge, which is hard to get it right. It would be very hard to cut that section out after the fact without hating the result afterward.
