True but it should be common practice to keep easily accessible copies
of all disk "metadata" (fdisk -l, tune2fs -l, vgs, lvs, pvs, mdadm
--detail, ...) for every box.

This is not relevant. The digikam software misusing UUIDs and not
accounting for your use case has nothing to do with using UUIDs to
mount disks through fstab.
