It'd be even better if you could ship a version to the App Store with an embedded JSON. That way you'll always have some version of your app. Or does it do that already?
If you wanted to version apps, I think you could version it at git level, or just think of it as an API deployment. No?
Still, very cool!
Or one could fork the code and change a couple of lines to make this work, technically it would be just a couple of lines of code, but I think policy-wise it needs to be thought out.
Please follow the project and feel free to start an issue thread, we can discuss further! :)
