My last skim of casync suggested that it's heavily block-oriented. That's fine for backups and FS duplication, but as a distribution format it doesn't really fly.
A lot of folks want two levels of insight into the image's provenance or trustworthiness:
1. Has the image been tampered with? This is mostly solved by TUF / Notary.
2. What are the files and where did they come from? This means you need a file-level abstraction that is simple and fast.
Insofar as casync is block-oriented instead of file-oriented, it's a poor fit for the second problem. It doesn't matter how efficient the streaming and storage is if you make people download the entire layer each time you want to check a single file.
