which makes it unsuitable as a full-fledged generic Python serialization
format, at least OOTB (Django knows how to get model objects back from
json, and I think one could write a more generic json serializer /
deserializer with about the same limitations as pickle).

I indeed assumed (possibly wrongly) that this would be enough, given the
use of a relational database. But as I said:

Not the same thing.
