I believe that a class G ATZ of increased dimensions would be more restrictive than class D, not less. RAS separation standards (3nm/1000' between identified traffic) would apply between the majority of IFR passenger transport a/c and VFR transiters, whereas with a class D zone the separation can be reduced (isn't even
required at all, strictly speaking). In both cases clearance to enter would be required. I imagine this'll be where someone suggests class E, but where the issue is conflict between unknown VFR against IFR traffic on an instrument approach, class E completely fails to resolve this.
