I don't think there was a consensus about that.

For ZODB objects I think its okay for now not to use deprecations and
to use the upgrade tool, but for the imports of other things that were
moved elsewhere, I still think we need to bug developers that they
need to upgrade their code with deprecation warnings, so we can
eventually remove old imports. Oh, and BTW, if we use the "zodb fix
tool", it's also okay to raise deprecation warnings about ZODB
objects, as it's really easy to fix with the magic tool and again, we
can eventually remove the deprecated import and make our code more
clean.

Let's discuss it once again :)
