I think it would make sense for launchpad-buildd to pass debhelper's new build option for PPAs, since it's narrowly-targeted and Launchpad is in a reasonable position to know what server facilities are provided. It's true that we historically used `/CurrentlyBuilding`, but passing narrowly-targeted build options is much neater; in the (very) long term I'd like to be able to drop the `/CurrentlyBuilding` hack.
