I even wonder if you can cancel some specific goal using the rclcpp_action API nowadays. You can see this: https://github.com/ros2/rclcpp/issues/747

Cancelling everything is an alternative:

  client_ptr->async_cancel_all_goals();

I even wonder if you can cancel some specific action goal using the rclcpp_action API nowadays. nowadays (Aug 2022).

The problem is that the "async_cancel_goal" requires a goal handle, but the "send_goal" function only provides a "future goal handle". You will get the required "goal handle" only after the response from the server is received. Too late to cancel.

You can see this: I would say that is still an open issue in the rclcpp repo: https://github.com/ros2/rclcpp/issues/747
