   > Generics is a very tricky area of the compiler. The diamond inference may 
assume that the target type's generics exactly correspond to the constructor 
type's generics. I don't think the `>` check is sufficient. You may have a type 
like "class C<V,K> implements Map<K,V>".
   
   Can you share a bit more on `You may have a type like "class C<V,K> 
implements Map<K,V>`? This PR is about when subclasses have less type 
parameters.
   Are you suggesting the compiler might wrongly inference class C as <K,V> 
instead of <V, K>?
