Actually it is not needed to wrap something to some class only for 
wrapping something to some class.

It would be more weighty reason to use Builder.

In such case I shall jast write

x = any_combination_of_rack_modules_you_like
Rack::Handler::ConcreteHandler.run x

In fact there is the one reason of using the Builder. To use already 
existing middleware which already have been developed for not so clear 
semantics of the Builder.
