Not really sure why
Not really sure why or what perceived problem this is solving.
Not trusting the environment that the server is running in. This is not even on my top 10 list of concerns.
Looks to me like someone who has been focusing on the side channel issues with CPUs is trying to make the fact the server is now running in a fixed envinronment is something you seriously care about. Either they are so deep into the issue that they can't see anything else, or it is Intel trying to make new CPU versions "important".
