If I understand the whole thing properly, the daemon already scans for
references and could register their location in the database, avoiding
the need for a potentially brittle in-store format as you highlighted,
although that would require a non-trivial change to both the daemon and
the database format.

In any case, I don't think it's necessary to treat packages in a special
way: any derivation can hold derivations and thus be grafted.

Best,
