Review comment:
While I agree that all of those things are useful sounding in theory, we
don't ostensibly need them right now, and I'd prefer to keep the changes
smaller. I don't like the idea of adding an interface with a single test
implementation on the hunch that someday somebody else might want to do
something else with it. If that's the case, we can refactor it in the future.
