Comment 2 for bug 1663742

no, I think on EC if you hit every primary and find *nothing* you can 404 - we probably don't even need to hit EVERY primary in a 15+3 schema.

But the question is more complex if you found 12 frags by the time you exhaust primaries... like you can probably guess the rest are out there... somewhere...

Ideally we'd respond with the data when we can.

The question is when can we say "yup, probably don't have this"

Replicas used to also not dig past primaries - then one day someone was like "yeah all three replicas were on handoffs after PUT because of 507's" and we were like, ok better dig!
