Well all Pythons need to change their (skin?) from time to time , isn't it ?

Sorry I didn't see your confirmation in the last msg you posted to the list .

Evolving the tests to avoid depending on these sorts of implementation
details is reasonable, IMO, and cuold even be considered a bugfix by
the Zope community.

Salomon says :

  - Problem could impact beyond Zope itself
  - unittest has been very stable (until now) so many solutions might be
    tightly coupled to its implementation details (e.g. formatting and reports)
  - so why not to include an option in order to keep runners compatible with
    < 2.7 ?

... changed somewhere and your tests suddenly don't pass anymore
