If someone is deploying mysql and wordpress, why should the database
necessarily be deployed in the same Ubuntu series than the frontend?
I believe there's no reason to not support mixed series, technical or
otherwise, and there are excellent reasons to support it:

1) Heterogenous environments are common place in the real world
2) It's an advantage the juju model buys on top of typical
single-machine packaging
3) It's very easy to support it
4) That's how py juju works

It's a valid question for sure. Thanks for asking.
