No matter how you decide to handle the transition, there will be
incompatibilities when transitioning between different data models.
Relying on a pickle is no different than relying on a JSON tree, an AMP
box or anything else.

Mapping the natural 2.x string type to the natural 3.x string type was
a reasonable decision in that context.
