Instead of repeatly emitting data about which modules are deprecated again and again just warn about those deprecation once and then never warn about them again. This is a good thing to have, and will be needed as taskflow moves one of its classes used in cinder to a new and longer-term location and will emit deprecation about the usage of the old location.
