Two enhancements are required:
1) We need an overload of find(HttpRequest) which only takes String and METHOD
2) We need qualified exception types for each possible thing that may go wrong with the find() methods. The requirement is for better typing, not necessarily checked exceptions. Watch out for backward compatibility issues with versions of Http connector that were released against 4.1.x
3) The builder for the registry should use Supplier to allow delaying the computation and calculating a response per execution.
