Yes, that was my understanding of our decision as well. But which third-
party modules are we talking about? the zope2.11 packages had:

Depends: python2.4 (>= 2.4.3), python-tz, lsb-base, libc6 (>= 2.3), python-support (>= 0.90.0), debconf | debconf-2.0
Pre-Depends: zope-common (>= 0.5.21)
Suggests: python-unit, zope-book, zope-devguide

Did this change significantly for zope2.12? A quick scan through
http://download.zope.org/Zope2/index/2.12.17/versions.cfg revealed, that
appart from the zope eggs (ZTK, etc.) the following additional python
dependencies are required:

python-clientform, python-docutils, python-mechanize,
python-transaction, python-tz, python-zconfig, python-zc.lockfile,
python-zdaemon, python-unittest2, python-lxml, python-sphinx,
python-pygments, python-roman

To be honest, I didn't think about possible conflicts regarding these
dependencies yet. But to my knowledge, python modules keep backwards
compability much better than zope eggs do, right? In this case we really
should use external dependencies.

And what about ZODB3 (python-zodb)? Do the maintainers care about
backwards compability?

greetings,
