I'm not sure falling back to pip is a good default. You might rather be alerted to a package's absence on anaconda.org than to have it silently installed elsewhere, for example for use cases when you totally want zero pip installed packages. But I agree there's a lot of opportunity for improvement around the configurability of this sort of thing.
