I hadn't quite got the layering and data present in a bundle straight.
Now that I do I think its simply a bug in the generation logic.
That said, its a defect in knits that the parent isn't explicitly
listed; and to have regeneratable indices we need a single parseable
block of data that lists the parents - you are right that we can nest
delta using parents list indices
to get a composite which has both things, without forcing the lower
layer to know about parents-as-tuples or parents-as-strings etc.
