Yeah. My blog story mentions the deltas actually.

Yes, but you implied in your post that there was an issue, and the article author took that literally (it looks like without doing their own research, which is understandable).

Basically I think this sentence should just be deleted:

> OSTree's method of serving individual files would be detrimental to the performance of content distribution networks if there were a plethora of small files, as synchronization will hammer the CDN with multiple HTTP GET requests.

Now, a definite OSTree issue is *managing* deltas, but for the OS update case, it's really really easy to just run `ostree static-delta generate` before publishing. When you involve multiple branches, managing deltas between them gets a little harder but it's just a matter of scripting.
