I'm sorry, but as a 737 operator into several class G airports, I'm with Dick on this one.
I carry 170-odd passengers and have to self separate from several IFR aircraft into the airports I fly to (including FDS King Airs and other FIFO Jets).
Separation from the VFR aircraft is generally not an issue, as they don't conflict except approaching the circuit area. Separation from the IFR aircraft is often an issue as they perform similarly and climb and descend on the same air routes that we use. Class E in these areas would certainly be an improvement in the safety margins we aspire to in high capacity RPT.
Broome and Karratha became very troubling prior to the recent introduction of Class D towers - until recently they were Class G with dozens of Jet movements per day.
Sat-based ADS-B Class E? Yes please.
