IANA mac guru, but the OF in Old Worlds (OF 1.0.5) has support for
reading from block devices, parsing *some* filesystems (this but is
pretty crippled - for example, no fragmentation can occur on a FAT
floppy, because it just loads data linearly). It can boot from a
partition 0 boot block (example: first stage QUIK boot block for
Linux), or from an XCOFF file (example: ofwboot.xcf from NetBSD/
OpenBSD). The NetBSD ofwboot page goes into a lot of gory details of
what the problems are with Old World OF =) - apparently the biggest
one are rather inconvenient load-base and real-base. It certainly
understands iso9660 and FAT (somewhat).

I'm not as familiar with how PPC OF boots... how similiar is it to
Sparc?]
On the Open Firmware implementations on the PPC machines I worked with
you can load an ELF file directly. Open Firmware has support for
reading from block devices, parsing partition maps and it has support
for some filesystems.
So at least of the New World Mac, the Pegasos, etc. this is not
required. Perhaps we need such bootblock for the old world mac...
