There are two benefits of this intended change: avoiding the downloading and installation of heavy build-dependencies only needed for generation of architecture-independent packages; and avoiding the build-time generation of those architecture-independent packages. Existing packages that have properly structured their debian/rules targets already for the second case would get immediate benefit from autodetection, with no further changes. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
