		So that could result in "close this backend connection" not "put into error state" as a
reaction, right?

	Yes (I forgot or didn't know the distinction between closing a particular connection and
marking the worker in error)

	At present we don't mark particular connections for close just based on the status code without
marking the worker in error, right?

	Anyway, my question should have been

	"Should we close backend connections if we get 400?" 
	Seems reasonable at least for mod_proxy_http to avoid further possible harm on that connection.
