For further clarification, the "fixed inertial frame" is the parent_frame_id, yes? Should we add that field to sensor_msgs/Imu?
It appears to me that for clarity it would make more sense if the orientation were in a separate message than the acceleration and angular velocities, so that they can be independently stamped with different frames.
However since there are IMUs that publish fused data this may not make senseā¦ it doesn't appear to make any less sense than having an Imu publish on separate topics, one for angular velocity/acceleration and another for the magnetic field, however.
