If the notification message was changed to include the reason code, then the supplicant wouldn't need to do a scan in this case, which makes everything faster (unless you have accurate scan results from a background scan). Dropping a scan means everything works much faster. Background scans probably won't work for our app because we are transmitting about 2-3 (sometimes more) good sized data packets every ~40 msec. We would have to drop video frames to make room for background scanning, but that degrades the video quality, and that is noticeable.
