Hi
The latest Prism version does not ship binary files (as you have to build them yourself). The team is evaluating the fact of shipping binaries in future versions, and if that is eventually done, adding it to the CDN would be beneficial for developers. You can create a new item in the Issue Tracker and have people vote for it and your suggestion might be considered for a future version.
Please let me know if this helps.
