Right.  This way, we could have a userland program (such as sysinst) that:
1) asks user which device to boot from
2) figures out OF path and partition
3) writes that to boot-device and boot-file

As an added bonus, it could also automatically insert the 500 ms delay for 
spin-up to boot-command on models which support it.

And, of course, the ability to reboot from NetBSD into another OS without 
mucking with OF.
