(Larry Virden had one large paragraph which I couldn't figure out how to
quote the germane parts.  From.  The gist was "Now that ROM 01 has been passed
by, do you think expansion ROM is a possibility?")

There are vectors in the system for expansion ROM (the two most famous ones
are the ROMDisk and ROMTools vectors), but the first is for ROM Disks (which
are available from a few places) and the latter is reserved for Apple.  We've
been known to burn EPROMs internally and use them for debugging purposes, and
we don't oppose developers doing that.  However, they can't *ship a product*
that uses the ROMTools vector or they run compatibility risks.

I don't think ROM 01-specific expansion ROM is all that good an idea; I doubt
developers will be willing to ship a product that won't work with any new IIgs
computers from now on.  I could be wrong, though.
