You can do it for to-one relationships, as snapshot will contain the FK value that corresponds to the related object PK. You won't be able to do it for to-many. Hopefully we'll expose API for a more direct change tracking soon [1, 2] that should include all relationship changes and won't require decoding of snapshots.
