VFR don’t broadcast on any “area frequency “. There is no need as they are flying at an ICAO 500’ cruising level. They are on the CTAF when in a particular airports approach and departure airspace.
No extra delays if you allow ATCs to use the same separation “standards” that are used by pilots in IMC in existing class G.
Yes it requires new rules.
Are you suggesting the FAA NAS system in non radar airspace results in excessive delays?
Why do you reckon the Americans are so stupid?
