WSGI middleware would by definition get the environ and be able to

Yes, not a problem for for middleware -> app communication. But some app -> middleware communication would be impossible if environ is completely read-only. I am assuming that "immutable" here means "read-only".

What if a middleware app puts a key in environ specifically for the app to write e.g., post-processing parameters? I have a use case for that.
