There is a uuid_msgs package [in ROS1](http://wiki.ros.org/uuid_msgs), would that meet your needs? We could consider either adding it to std_msgs as you suggest of port this package and add it to the common_interfaces repository --- [Visit Topic](https://discourse.ros.org/t/uuid-in-std-msgs/1941/3) or reply to this email to respond.
