But you said that it was OK for these aircraft to contact ATC to request flight following.
How will the universe know that a call is to request flight following rather than to announce rolling at Bowral sheep paddock, and arrange the laws of physics so that the request for flight following can never 'block out an important call'?
On the issue of VFR calls on Area, you consistently overstate the risk. I'm guessing that's because you don't understand the rules for broadcasts in the vicinity of unmarked, uncertified, unlicensed strips in ForG.
