(And inject it into the test -- possibly one test with and one test without to make sure the try/except also functions correctly.)  I feel that .yml is actually a much more natural way of defining the cluster list than json, because YAML supports basic templating in order to reduce redundancy, similar to pystachio.

If we are going to drop the PyYAML dependency then I think we should drop all of the YAML related code. I agree that YAML is a much nicer format because of the templating functionality it has but as it stands I think the cost of supporting YAML (native code, extra compelxity in loading) is greater than the benefits of a simpler config file.
