Only addressing the chainload concern,
According to the spec, the bootloader could use both normal configuration
AND boot fragments.
This means that chainloading can still be done the way it is done now, and
those boot fragments
will only be used to load OSs that implement this specification.

Since you don't need to update chainload settings so often as you need to
update regular boot
entries, this seems fine to me.

Regarding the Mac concern, I understand that it's incompatible because we
reuse the existing
EFI system partition on Mac hardware. Is that correct?
Do you have any suggestions on how this can be fixed so we can use the
bootloader spec?

Having a pile of shell scripts doing such a critical task seems extremely
error-prone and broken.
