Reminds me of how visual studio used to produce .net client code in vb or c# when you gave it a wsdl URL. You could do the same thing with Delphi. It had a command line program to generate a client interface. And a Ruby gem could just generate calls on the fly with method_missing. Turns out that having a web service definition language and concrete types to generate it automatically is a really useful thing. A thing that we somehow seem to have lost on the road.

Yeah totally agree - unfortunate that OpenAPI so much flexibility that there are multiple ways to define the same operations. For api users having the concrete types just means faster integration, no ambiguity on what is/is not supported.
