Sure.

Though, `stubout` and `mox` are used across a bunch our tests already. My completely non-scientific opinion is that dependency-injection is used much less frequently. So, there is a risk that we're making things worse by having two separate ways of achieving the exact same thing.

Personally, I'd prefer we settle on using stubs, but that might be a question better suited for the ML.
