On the other hand, it seems that the BBB packages that would guarantee
the pickle to be loaded were not included in the release

And yes, no generation scripts were written. Why? Because

a) there doesn't (yet) seem to be an API that lets you iterate over
objects (perferrably of a certain class) in the ZODB so that you could
have them repickled (at least that's what Jim told me when I asked him)

b) no persistent class was moved for this reason. Of course,
non-persistent classes might still have been pickled. However, IIRC even
if we had such an API described in a), it wouldn't be of any use because
the objects that were moved don't have their own pickle but live in the
pickle of some persistent object that makes a reference to it.

As said, BBB packages were provided, but not included in the release.
This is a packaging problem.
