I think we could have added those packages in a namespace. What if we want to extract similar things out of Zope 2 core. For example DTML related things could be extracted out of Zope 2 core. I guess we are planning to improve the WSGI story of Zope 2, in addition to creating new packages, we will be required to re-factor existing code for this. I hope these kind of "refactoring" would be much easier with namespace packages. One of the major contributing factor why we were able to create a nice ZTK out of Zope 3 is the use of "namespace". There are few more important factors: - We should not clutter top-level names with Zope 2 specific packages This is very important in the context of new distribution mechanism we adopted (egg, PyPI). Courtesy to other PyPI users ? - Branding Zope technologies is also very important. Yes, Zope is still a good brand :) - Some of the things mentioned in this blog by Martin Aspelli: http://www.martinaspeli.net/articles/the-naming-of-things-package-names-and-namespaces PEP 20: "Namespaces are one honking great idea -- let's do more of those!"
