Just read this going throuhg 3 months of backed up parted mail.  You
make a very good point but I think going agains the spec is not the way
to go.  This would increase the possibility of incompatibilities with
other UEFI spec implementations other than what parted has (which I'm
not al all sure it complies 100% :)

For me, this is a big question mark ATM.
