If we simply put an MBR in sector 0 that does not cover sector 1 at all (or any subsequent sectors that are part of the primary boot image), I don't think we need to bother at all with GPTs or protective MBRs or anything else that is specific to UEFI. Let's just start the first partition at the next eraseblock boundary, and make it around 128 MB in size, so we can use it as the EFI System Partition (ESP).
