People have reported that they have not finished opening their laptop screen and they're connected, so at that level of latency, every millisecond is important and totally worth fighting for.  Randomizing the MAC would penalize our connection times by 2X (300 ms at least).  And Android folks have reported the penalty to be as high as 3 seconds.  So this needs to be fixed.  And do note that this is a feature every modern OS implements by default.

Hi Bob,

Thank you for your post, but this is an opinion and adds nothing to
the technical discussion underway. Let's discuss the patches please.

Thanks,
