Because no bsd runs on the raspi as yet but linux does!  There
is no u-boot or netboot on it either. The GPU loads a file
called kernel.bin from a FAT partition.  So the idea is you
boot linux on the raspi, scp an elf binary file you want to
boot from (or nfs mount a freebsd filesystem on it) and
kexec() this file. It is upto the binary what happens next.
This binary can be *BSD or netboot. In fact different people
can work on each in parallel. Once either is ported, you
can bypass linux.
