If we were able to come up with examples of BIOS/UEFI that cannot boot from GPT partitioned volumes there would not be a problem as long as bsdinstall still supports partitioning volumes with MSDOS/MBR partitioning schemes. The big problem is being able to launch the installation process to start with which is yet another reason to have the memstick image non-GPT even if you could work out a script/kludge etc to be able to write a properly formatted GPT memstick. The solution to this issue is obvious.
