Except for the sky high complexity cost, you could expose a scripting api that could connect to the database and inspect things that didn't use rust.

I don't know if that's a good idea, but for much of what I personally used the django shell for (did this record get written the way I expected) it could help. Wouldn't help for situations where you want to monkeypatch the running app at runtime (but it's arguable whether you'd want to do that anyway).
