Comment:
I want to help you advance the django-async-backend, but I'm not certain
that it needs to support WSGI right now in order to advance. I'll leave a
comment on the [https://github.com/django/new-features/issues/7 new-
features repo issue] that tracks that work to get more input. I could be
not understanding the intended audience of testers. Can't we test this
with `daphne`'s runserver?
About why it was designed this way, I did find a reference in the
[https://github.com/django/deps/blob/main/accepted/0009-async.rst#high-
level-summary async DEP] about the intended final design:
> WSGI mode will run a single event loop around each Django call to make
the async handling layer compatible with a synchronous server.
So that supports the idea that we would eventually get around to your
proposal, but since DEP 0009 there have been other conversations to the
effect of, "aren't we basically done except for the async database
backend." And if that's ASGI-only for now, that might be enough?
I can check my understanding with the Steering Council early next week.
Setting Someday/Maybe until then.
