I was a little confused by your reference to common_msgs, as I'm only concerned about ROS2. It seems that common_interfaces is the right place to include the uuid_msgs package in ROS2 (leaving the message type & name & package as unchanged as possible from ROS1). That way we don't need a separate repository for one line of code. --- [Visit Topic](https://discourse.ros.org/t/uuid-in-std-msgs/1941/7) or reply to this email to respond.
