Class E is not for the benefit of VFR aircraft.
Class E provides additional services to IFR aircraft over what they would have received in G i.e. separation.
I'm not surprised if the Avalon airspace is being reviewed. It appears to have been designed to fail. It has been located to provide no benefit (or even lesser service) to IFR aircraft rather than benefits. Given the ongoing opposition to Class E as used e.g. in the USA, I suspect it was set up so they could say "Yes we tried it", without any chance of success.
(I was out flying today. With multiple IFR aircraft operating in G, ATC go on ... and on ... and on giving traffic information to everyone. It takes them so long - are you SURE it wouldn't be more efficient to give clearances?)
