What do you want your nginx to do, in that case?

I suspect that what nginx does do,  depends on things like

As you suggest: if nginx gets the entire response before sending anything
to the client, it can send a suitable response code.

If nginx is told to stream the response "live", then if the response is
http 200 plus half the intended body, that is what the client will get.
