To balance that a bit, the issues with rosbag2 right now are so great that you couldn’t build a product (or even research) around it. It’s been a reoccurring issues in Nav2 / SLAM Toolbox that rosbag2 is blocking data sharing in ROS2 because of performance issues and reliability problems. I’d usually agree with that argument, but in this case, I think its degraded to a point that these aren’t modest improvements, they’re making it usable from being unusable.
