I've had a stab at creating a simple WSGI deployment implementation.
I use the term WSGI component in here as shorthand to indicate all
types of WSGI implementations (server, application, gateway).
The primary deployment concern is to create a way to specify the
configuration of an instance of a

In many cases, the middleware is modifying or watching the

My understanding from reading the WSGI PEP and examples like that above is
that the WSGI middleware stack concept is very much tree like, but where at

I've also been putting a bit of thought into middleware configuration,
although maybe in a different direction. I'm not too concerned yet
about being able to introspect the configuration of an individual
component. Maybe that's because I haven't thought about the problem
