This specification is ill-designed with the express intention not to use modern ways like multiboot. Unless there is a use which isn't covered by adequate ways, it's counterproductive to implement it. If you have usecases please use grub-devel

When the top-level partition map is GPT, the chainload command
should pass an hybrid handover structure, as documented in
section A.4 of the ``hybrid MBR boot code annex'' [1]. Without
this support, the chainload command is useless for GPT since the
VBR boot code won't be able to locate its partition (even if it
supports GPT).
