I suspect for most WiFi users, the overwhelming need is more reliable and fast establishment of connection. I waste vastly more time trying to deal with flaky connections, reconnection after wake from sleep, and network priority issues than I do waiting in the rare cases the WiFi is limiting thd data transfer rate (rather than the wired connection).

The timescales involved in making Wifi connections should be ms or less, not human-noticeable (order 10 sec).
