By fallback datasource, you mean "None"?

We could always reintroduce the use of debconf for datasource selection,
and avoid depending on ds-identify at all.  The nice thing about that is
that we could then pre-fill that answer in our cloud images and
configure an explicit datasource there, too.

(Note that I don't actually *like* the idea of reintroducing debconf...)
