I suspect this would make GC inefficient (lots of disk seeks to
determine references/referrers compared to queries of the SQLite
database.)

Another (opposite :-)) option is to make /gnu/store a read-only bind
mount on GuixSD.  Commit 3392ce5 does that.  This will prevent
accidental modifications of the store.
