I think app.ready is considered module loading time and thus query should not be performed during that time.

Given the explicit warning in the docs I'm inclined to close this ticket as wontfix.

I totally agree with Simon, we've already warned in docs about running queries in app.ready() and we shouldn't encourage them is ASGI.
