Speaking of UUIDs, I must that it is possible to use partitions UUIDs
(root=PARTUUID=...) without initrd and that is, regardless of
distributions.
That is correct. Plain UUID is for the formatted partition UUID and
does require a initrd. PARTUUID is assigned when the partition is
created and before the partition is formatted.

I do think UUID usages require a GPT partitioning scheme
Also correct because MSDOS *partitions* do not have UUIDs. The
underlying partition formats do have UUIDs.

but I have no
way to confirm this because all my systems are EFI (Mac Pro 2006) or
UEFI (all the other computers I have).
