Not quite right as far as I know. It was primarily intended for
EFI/UEFI, but now runs with BIOS, too.

But first installing a system and then make GPT partitions wouldn't
make much sense particularly if you need to install the system onto a
partition bigger than 2 TB even if this partition only contains /home.

There should not only non-boot GPT partitions. It should be possible
to be able to building the whole partitioning scheme as GPT.

I don't know if it would be possible to mix MBR and GPT partitions
