I agree with the sentiment but I'm struggling to see how this qualifies as a legitimate tradeoff to make. I thought the entire point of this feature was to provide assurances to customers that cloud providers weren't snooping on their VMs. In which case physically interdicting RAM in this manner is probably the first approach a realistic adversary would attempt.

I can see where it prevents inadvertent data leaks but the feature was billed as protecting against motivated adversaries. (Or at least so I thought.)
