Having WordPress in Maintenance Mode (using the official WP Maintenance Mode plugin) returns an HTTP 503 error (along with the placeholder that I don't want to validate). I am supplying the user/pwd to CSE, and am not using HTTPS (so don't need a proxy setting).
I am not sure how difficult or feasible it would be for CSE to be able to log into Wordpress in Maintenance Mode, but I think it would be very useful.
