Yes, somewhat true. But I still use carefully managed labels
instead of hard to remember UUIDs and it you lose it, its a pain
to recover. It's easier for me to see: f11-boot, f11-root, f-App1,
u9-boot, u9-root, ..., w2kPro, w2kSvr, VistaH, XpPro, and so on.
I have many different OSes dispersed over many HDs.
As for grub itself, I use a grub "tree-structure" and the primary
boot grub so happens to be based on F8-grub and on the drive's
1st partition, followed with whatever grubs each OS supports
and each in it's own boot/root partitions per drive and usually all
in the extended partition. All of my OS SATA drives uses the
maximum of 15 partitions, so that the tables are always
preserved, I learned this the hard way.
All in all, it works very well.
The point is, labels and/or UUID are not a requirement, but a
perhaps convention? This could change though, but I hope not.
FWIW
