Circular dependencies should not prevent piuparts from testing packages. 
That's simply a bug in piuparts for not knowing what to do with them.

Forbidding something that has always been supported and that has a number of
useful (and important) corner cases should not be the role of policy. 
Please demonstrate first that the use cases for which circular depends are
used have been adequately addressed, *before* ruling it out in Policy.

If there are a limited subset of problem cases where circular deps are still
needed, it would be fine to have policy enumerate these exceptions and
forbid it in the general case.
