I very much want Zope 2.9 to use Zope 3's security architecture. Zope 3's security architecture is far more robust, but it is different in some significant ways:
Even small modifications to the security machinery tend to end up in lots of problems.
The latest prominent example: the changes introduced with Zope 2.7.3: It took two releases (until 2.7.5) and more than 6 months (at least in my memory) before everything worked again as it should...
Hopefully, such a major change will not require 4, 5, 6 minor releases and years for stabilazation...
Hopefully not. It depends on whether people choose to test their application during the beta cycle or during the release cycle.
This will be a *big* change. Possibly, this will be bigger than the change from 2.7 to 2.8. I do think it will provide significant benefits that justify the pain. Of course, when we try it, we may find it is too painful and we'll have to reconsider.
