The purpose of the extension if to just have a standard interface that WSGI applications can use to take advantage of the possibility, offered by asynchronous server, to suspend execution and resume it later.
WSGI has this ability now - it's yielding an empty string. Yielding an empty string is a hint to the server that the application is not ready to send any output, and the server is free to schedule other applications next. And WSGI does not require the application to be rescheduled any time soon.
In other words, if saying "don't call me for a while" is the purpose of the extension, it is not needed. As Graham says, the thing that would actually be needed is a way to tell the server when to poll the app again.
