Actually, a lot of people spent a lot of time
reverse-engineering the
IBM BIOS. You really don't get a sense of this until you realize
that Phoenix not only made sure that the functionality of the BIOS
routines was the same, but that the routines themselves were located
at the same place in memory.
I wonder why this wasn't done with the Mac ROMs? Fear of Apple
suing? Anyone know for certain?

Not for certain, but I'm sure relative market share had a lot to do with
it. I'd say another factor was that the mac ROMs were quite a bit
larger than the PC BIOS of the time (512KB vs 40 KB).
