I agree with you. It's just to get them close either with stuffing the board, or making the PCB.
Who cares if a surface mount part has a couple through hole alignment holes? They are holes nevertheless and require drilling, so they need to be counted as through holes. Here's a sample from one of my recent boards. I consider this to have 6+(750-608)+190=338 "through holes" and 608 SMT pads. 6 of the through hole pads are not plated. What's the big deal?

I can't believe that a quote based on a QFP being costed the same as an 0805 is anything but budgetary... Sounds to me like sorting the BOM based on footprint will get the answer as accurately as is needed for this...
