My current proposal un-wedges all of our Xenial testing; py3 would be great as well, but if we can maintain a charm that supports both cases that would be awesome.

+1 on this work-around and the mongodb change to un-wedge xenial. It's not deployable at all after the python27 removal in xenial-dev, and that blocks a lot of other things that are inter-related on mysql and mongodb.
