Feature description
Since a subscriber can receive a topic message only if its QOS profile is compatible with the QOS profile of the publisher a method to retrieve this information from the available topics should be very useful.
Implementation considerations
I think that the command
$ ros2 topic info /topic
can be a good place to introduce this important feature.
