btrfs subvol show <pathtosubvolume>

It will show the subvol uuid, and if it's a snapshot it will also show the parent uuid. If you mean partitiontypeGUID so we have some idea what the purpose of these subvolumes is, like the unique partitiontypeGUID for home? Could be useful. Certainly there could be some additional metadata for tracking the relationship between many subvolumes as well as purpose.

Possibly a snapshot family, that describes multiple subvolumes; and then use that information for a systemd mount job, it would make fstab mostly obsolete.
