That's great. I love open sourcing things, so in a perfect world I'd never have a private repo. (for a side project that is) Unfortunately, I have third party assets that I cannot release under an open source license, that I would like to use for my side projects, and I would like them to be versioned alongside the code. That's not an uncommon situation for people who enjoy writing games on the side, for example.
