The effect on my system's grub.cfg is to turn all the lines that
looked like:

 linux /boot/vmlinuz-4.19.0-18-amd64 root=UUID=fedcbaff-1234-5678-ab90-ffee88771234 ro quiet

into:

 linux /boot/vmlinuz-4.19.0-18-amd64 root=/dev/sda4 ro quiet

and I don't see how that helps your using LABELs. (The last thing
I want is the kernel's "randomly" chosen device names.)

Or does this mean that the functionality for handling LABELs has been
added to the scripts in /etc/grub.d/, in which case I would be
questioning why it wasn't activated with:

  GRUB_ENABLE_LINUX_LABEL=true

rather than:

  GRUB_DISABLE_LINUX_UUID=true

Cheers,
David.
