Which sense of "should" do you mean here?  That doing so would be 
inappropriate, or that it just doesn't ever happen?

The code this patch removes seems appropriate to me.  Perhaps we don't 
currently call this function with reference types, but unless that is 
part of an interface specification, it's better to be robust and handle 
any input.
