Doesn’t seem like a fundamental flaw in the IEEE 802.11 spec, but rather an implementation issue. For example my previous startup (Anyfi Networks) implemented 802.11 in a split-MAC architecture where all encryption is done “in the cloud” and raw encrypted 802.11 frames are tunneled over IP. In such an architecture frames are encrypted long before being put in the power save queue in the access point.
