I can understand that writing up technical details can be difficult as things are constantly improving and also as AWS has to be careful about what they claim.

I can understand that writing up technical details can be difficult as things are constantly improving and also as AWS has to be careful about what they claim. Perhaps a reasonable compromise would be to team up with some 3rd parties to let them try it, optimize a bit with techs from AWS and write up their experiences. Similar to how Apple does the marketing for the iPhone but then lets other people review it. Not perfect but perhaps something that would help the community understand and deploy these technologies better.
