      //      IMPL NOTE : yes if we get here this impl is very non-performant, but PersistenceContext
      //          was never designed to handle this case; adding that capability for real means splitting
      //          the notions of:
      //            1) collection key
      //            2) collection owner key
      //           these 2 are not always the same (same is true in the case of ToOne associations with
      //           property-ref).  That would require changes to (at least) CollectionEntry and quite
      //          probably changes to how the sql for collection initializers are generated
      //
      //      We could also possibly see if the referenced property is a natural id since we already have caching
      //      in place of natural id snapshots.  BUt really its better to just do it the right way ^^ if we start
      //       going that route
