The only worry I can think off is when somebody wants to install without
using LVM. So the installer sees /dev/sdb, and puts that in
the grub.conf for the kernel root device (root=/dev/sdb).
For many years "root=LABEL=/" has been the anaconda default for kernel
commandline parameter, (at least when not using LVM.)
This was motivated by the possible renumbering of [SCSI] drives
even when _adding_ a new good drive. There still are grub.conf
stanza lines such as
splashimage=(hd0,0)/grub/splash.xpm.gz
and
root (hd1,0)
which do name physical partitions [frequently not whole physical drives.]
