Ahh I worded my question very poorly. I knew about the subscription backups but that's a non-starter for me. I admittedly tuned out during that part but are they backing up the full device memory in that subscription or just the keystore? I was looking more for a way to export an encrypted blob of the filesystem manually without relying on Foundation for anything in the future but still keep my files/auth keys.

I heard them discuss the app store but missed the side load part. That's huge win. Still hope there's an option for using a third party store instead of using Foundation's repos.
