    I disagree. DeleteQuery works just like SQLTemplate in regards to
    object graph - this is a direct db operation bypassing ObjectStore.
    It was used by Cayenne internally before batch commit queries were
    introduced in 1.1. I was thinking of deprecating it, but I am still
    undecided as I can see its value as a utility query.

    True, it can be used to delete bulk data, but preserving object graph
    integrity will be responsibility of the developer (e.g. via invalidate).
