They aren't well-enough "battle tested" to make Andrew's point invalid,
I think (there *are* no "large" ZODB-based Zope3 sites which have
undergone generational upgrades).
Frankly, anything which attempts to "fix pickles" in-place smells bad to
me. "Dump and reload" is how the RDBMS world handles this kind of
problem, and it isn't because they don't have smart folks working on them.
