Even web microservices are not necessarily RESTful ones. Nick has 
correctly pointed out that there is a lot of spiritual similariy 
between concept of microservice and traditional UNIX way of 
designing small single-purpose command lines apps. It basically 
gets down to "do as few things as possible in one application 
(but do it good) and build a pipeline".

What utility would you expect from such framework?
