I have implemented this one by creating a new 'zope.broken' package, and making 'zope.container' and 'zope.app.broken' depend on it: - The 'contained' module has a bunch of dependencies, including a suspicous one on zope.app.broken: if the IBroken check is really needed, then that interface should be moved to another package. and this one: - The zope.exceptions dependency, again from contained, is due to the use of a couple of dubious zope-specific exceptions: o UserError should probably be replaced with the standard ValueError. o DuplicationError should probably be replaced with KeyError. now released in zope.container 3.7.1 and zope.app.container 3.7.1. I also updated the 'zope.app.zcmlfiles' package (now version 3.5.3), which was not including the 'zope.app.broken' package in its dependencies, although it pulls in its ZCML.

Re: [Zope-dev] dependency cleanup progress report
Hey, Thanks for this feedback. It's a good sign that such feedback is now possible due to us having a saner dependency graph! We won't be taking action on these issues during this sprint as we're trying to wrap it up and make releases of our changes. At least the dependency graph for zope.container has no more cycles (they're still abundant elsewhere but we have a better grip on them now at least). hat shouldn't stop anyone from trying out Tres's suggestions, which all look like good ideas. When you try these things it's a good idea to test the trunks of various packages against each other, so do consider using z3c.recipe.compattest with use_trunk mode to make sure your changes don't break anything.
