That's wonderful...
Now, how is the average pilot supposed to know that there is such a thing as
an 'Approach Watch Desk'? Or, that FSS is the part of the system which has
the phone numbers for 'supervisors' identified by this internal jargon
within ATC? Where in the AIM is this information contained? How many CFI
or CFII folks give their students this specific information?

Rhetorical questions to make a point...

Get the direct dial (866) number for the AFSS that serves ATL.
Ask the briefer for the telephone number for the ATL Approach Watch Desk.
Call the Watch Desk and discuss the matter with them directly.
