In fact, delete photos (and now videos) from the local cache is very important to keep the internal device space under control, in two cases: (1) after Cloudinary upload or (2) when you are storing data 100% locally and want to delete it!
And if I understood correctly in this post, another issue in PhotoLibrary block is that after you update the app on iOS you loose all local photos.
@jared, how about to set this post in the feature request, and the other I mention as ISSUE/BUG ?
