This is actually my bad, I recall it was me the one who accepted those changes in the roadmap. I’d say, feel free to suggest changes directly @gbiggs, input and contributions are more than welcome as we said in several threads.
Does that actually exist? I use actively https://index.ros.org/doc/ros2/Contributing/Migration-Guide/ but I’m not aware of a ROS 2 glossary. Which by the way, it’s a rather good idea, even beyond the MoveIt! 2 port.
