Retrofitting classes as records in the JDK

The method cannot be removed.  Under the current spec, it _must_ be 
public.  Under the spec current in revision, the rule will be relaxed 
that it has the same accessibility as the class, but can be made _more_ 
accessible, but not less.  It is part of the API; removing it / hiding 
it would violate this.

You can implement it to through UOE, but in that case, you should 
question whether you should be using records in the first place.
