I'm not quite sure about this one, GPT disks can have an msdos compatibility
table at the beginning of the disc (created using gptsync), and some EFI machines
can boot from msdos labelled disks.
The first chunk should be fine (even if the MSDOS compat table is
there, we'll see it as GPT). The second one, yes, having this will
break installing on Intel Macs booting via the BIOS emulation vs going
through EFI. And given some of the oddities of their EFI
implementation, there are some advantages of not booting from it
directly
Hrm? How will it break booting through their CSM? self.isEfi will be
/False/ in that case.
Hans is right that some UEFI machines can boot from MBR/MS-DOS partition
tables, but a) those machines can also boot from GPT based tables and b)
we don't have any way to know if we're running on such a machine. I
think always requiring GPT for /boot/efi is probably the right thing to
do, especially since we can't actually tell when it is (or isn't)
required; the safe plan is to assume it's always required.

When in doubt, make a fool of yourself. There is a microscopically
thin line between being brilliantly creative and acting like the
most gigantic idiot on earth. So what the hell, leap.
