Has power use been a consideration and been measured?

I can imagine that pushing more logic to software and handling packets in smaller batches could be detrimental to power consumption.

Not explicitly. However, while we are theoretically doing more work per packet, we have not seen anything that even registers on the CPU usage monitor. Crypto is still offloaded on most hardware, and most of the power save features of WiFi work by letting idle stations sleep for a while to conserve power. That is unchanged; these changes only really kick in when a device is busy.
