This allows for a method group with both methods from extension and underlying type.

```
var a1 = EDerived.M2; // method group should incorporate members of EDerived, EBase and C

EBase.M2 is private
EDerived has a Method (also private) but not M2

Based on the comment I expected to see M2 from a few types but only see one that would be applicable here. Not sure how Method factors into this.

Why? I mean I'm glad that struct can be used but unclear what ref struct was stopping in terms of downlevel support.

We instead want to treat the underlying type as a base type. It still comes into play last (meaning after all base extensions) but not conditionally.
