I'm conscious of having set out to fix an annoying bug in the Gnus
registry, then moving on to re-write most of eieio-persistent, and now
apparently mucking about in the guts of gv-ref/gv-defer, which three
weeks ago I didn't even know existed. Mission creep is real! Maybe we
should be opening a separate bug report so other people can comment on
adding a unique tag.

An intermediate solution could be to write a `gv-ref-p' inline that's
only meant for use with `deep-edit'.
