Comment 2 for bug 1392544

After investigating with 1.21 and looking back to the history of "juju get" implementation changes, I can confirm this behavior is by design, ever since pyjuju. It's unfortunate the name "default" was chosen, rather than "is-default" or something, to make it obvious it's a boolean flag, and not the same as the "default" field in the service config. I'll propose a fix which updates the juju get help information to explain the output of the command.
