Also GPT partitions have little use when using mdraid/dm-crypt/lvm2 (or zfs) stack. IIRC Windows have similar features with dynamic partitions, so I don't see any reason to use bios partitioning for anything beyond boot (and MBR is enough for it, even without extended partitions).

GRUB on GPT+BIOS requires the use of a BIOS Boot Partition too (type code ef02 in gdisk... see the full UUID for the full story). So one of the points is moot as well.

More specifically, BIOS machines don't know what partitions are (nor partition tables), and it's only the first 446-ish bytes, not 512.
