I'll leave my ros_ign-release fork up as an example, but bloom uses existing branch names to find which packages to generate for, which means that packages dropped from a distribution are still released:
The way to mitigate this is to add a $TRACK.ignored file and ignore the defunct packages. Placing a COLCON_IGNORE or CATKIN_IGNORE in the upstream repo instead of removing the directory completely may also work.
