I think this is a great idea!

I wonder if it would be smarter to collect all these in one geom
class rather than have one for each volume label metadata format,
having it in one GEOM class would simplify name-collision handling.

On the other hand, name collisions are already passively neutered
in DEVFS, so if we can live with "Don't do that then" handling of
it, then there is no reason to not have them as different GEOM
classes, which certainly makes for simpler and cleaner code.

(Summary: Do it whatever way you prefer :-)

PS:
I would love to see handling of ISO 9660 (CDROM) volume labels as well.

PPS:
When you commit, please put it in a subcatalog under sys/geom.
