Afaik it is also required in case one uses EFI instead of a BIOS. Doing
this soon would make Fedora ready once it is required. Other nice
features are checksums for the partition table and file system
independent uuids for the partitions and file system independent clear
text names for partitions. These can be used to easier identify
partitions that do not contain a file system, e.g. because they are
encrypted or they have been wiped. Then they could be easier identified
to be used again, e.g. in the installer.

For large disks it would be required anyhow. But it does not need to be
default, at least support for it in the installer would be nice.
