Yep. You should also be hosting and deploying from wheels[0], even for stuff you create internally. If you're doing it right, you'll end up hosting your own internal PyPi server[1], which, luckily, isn't hard[2].

We did this at one of my previous companies, and, of all the things that ever went wrong with our deploy processes, our internal PyPi server was literally never the culprit.
