Right, I'm having issues too with the config file not being initalized.
I'll have a closer look.

I'm not exclusively using the REST API though. I'm importing a couple
interfaces, mostly the archiver interface. I'm also using the custom
Message class a lot in the tests. And I'm importing a couple database types
for compatibility in my own schemas (Enum and UUID)
But I think the main problem is the import of mailman's config object in
the class that implements the IArchiver interface. I don't believe there's
another way to get the configuration.
And now that I think of it, the archiver interface will be imported by
Mailman core, and will thus run with a Python3 interpreter. As a result,
all of KittyStore must at least be Python3 compatible.
