Roger is aware of this, since we use this feature in z3c.form* development all 
the time. However, often you do not even *know* what other packages are 
affected, so I cannot test them together. With the trunk, you always have 
this check.

Further, when working on zope.app.session, it does not even make sense to add 
zope.app.authentication as a develop egg, since it is not a dependency nor 
will be tested.

The issue Roger has here, and I agree with him, is that you do not notice 
these type of problems until you are working on a project that requires both 
packages. But not all development is project-driven; for example a sprint.
