There are two parts of this question:
1) Which partition schemes should GRUB be able to read modules and

and 2 conditions apply:
- Usage. There are OS which are able to boot from such OS and such
configuration isn't considered obscure by them.
- Non-confusability. The risk of false positive of this partition config
which would prevent normal function is small.
If at least one condition is met it's worth considering. If both
conditions are met it should be supported.

Ok.  Regarding confusability, I can see potential problems in the
interpretation of offsets (absolute or relative?), such as for nested
BSD labels (discussed in another thread).  Do you see other potential
causes for confusion?

2) Support for embedding.
Embedding is a potentially dangerous operation so we have to be
cautious. Using a dedicated embedding partition if it can be
unambiguously identified as such is a sane solution.

Sure.  As discussed on irc, this would require in-depth changes to
grub-setup, and it's worth another thread...
