I'm kind of worried that we're not using a common network layer. I'm not sure if this is a temporary thing or definitive.
One issue I can think of right now is that this might not set the [User-Agent](https://github.com/wordpress-mobile/WordPress-iOS/blob/develop/WordPress/WordPressApi/WordPressComApi.m#L77) or other custom headers.
Or that we have some custom code to [interpret JSON errors](https://github.com/wordpress-mobile/WordPress-iOS/blob/develop/WordPress/WordPressApi/WordPressComApi.m#L94)
