TBH I think that the best would be generic support for partition table
manipulation (or at least creation); then we'd have easy tool to adjust
and test various layouts. It could be modeled after boot support,
something like

-partition <type>,<number>
-partition-range
-partition-type <number>|<UUID>
-partition-guid
-partition-label

where -partition-range would support selection of files and data ranges
from image. Similar to -append-partition but with reference to existing
data.

Otherwise the most safe approach is probably based on design of mjg

MBR with single ESP
GPT with single ESP
APM with ESP, HFS+

This means that GRUB will not use GPT, but still be able to access ESP
via APM. GPT is there for those systems that ignore MBR (I trust mjg
they exist). We do not need special partition covering the whole image
as GRUB will work with iso9660 on the whole device anyway (and we always
can mount it as whole device in Linux as well).
