Sure, sure. The more testing the better, and we have to test those
libraries anyway. The point I was making was that *relying* on these
dependent tests to find out about interface changes in dependencies is
not very satisfying. It's at best an indirect way to discover such
changes, with poor coverage of the dependency's interface, and we ought
to have a more direct and reliable way to address the problem if we can
think of one.
