Yes, requirement of get_instance and service is the spec
of WEBrick::HTTPServer. I guess it will not be changed.
# at least in Ruby-1.8..

By the way, the code of servlet activation is described in
HTTPServer#service. We can rewrite it to build specific
purpose server or realize another idea about uri-to-service
mapping.

   require "webrick"
   class NotFoundServer < WEBrick::HTTPServer
     def service(req, res)
       # returns 404 against every request.
       raise WEBrick::HTTPStatus::NotFound
     end
   end
   NotFoundServer.new(:Port=>10080).start
