I suppose the rare situation with many linux distros on one computer may
cause issue, but personally, I'd have preferred the partitioning utility
in the installer to offer the option to set/view labels instead (perhaps
next to the option to generate a UUID for the partition?)...
After all, the partitioning tool in the installer needs more features
anyway: such as being able to set boot flags (useful for dual boot
systems that don't put grub in MBR). It could also support explicitly
positioned partitions: currently, it orders you're partitions for you,
but who says I want boot partition placed before root partition or free
space? (This issue came up for me recently, when I found I was unable to
reserve space at the beginning of the drive for a Dell utility
partition: I don't remember the specifics but I ended up booting Knoppix
and used gparted before running F9 installer).
