Does anyone know what it would take to try to make this
case to the FAA to try to get them to change their minds?

I'd say about 20 years ... to change the FAR.

I was flying out of Jefferson County Airport in Colorado around the time
that the T.V. show Mork and Mindy was popular. There was a fella who often
was in the pattern when I was who's callsign ended with 99. He would always
say "nano-nano" to acknowledge a call.
