RHEL failures are unrelated https://ci.ros2.org/job/ci_linux-rhel/1473/cmake/new/ (RTI cmake) and https://ci.ros2.org/job/ci_linux-rhel/1473/testReport/ (python yaml). i will go ahead to merge this.

IMO this can be useful for the application that uses simulation clock. currently this is not supported, rcutils logging macro is not aware of simulation time (nor node object), so...

@InvincibleRMC can you address https://ci.ros2.org/job/ci_linux/21236/testReport/junit/launch.test/test_mypy/test_mypy/?

@youthantennalemon according to the log you attached, `keadm join` successfully completed without `Token is expired`? Is this reproducible?

issue title has a typo, > Add a Proposal about Privide a Common MQTT Mapper should be, `Add a Proposal about Provide a Common MQTT Mapper`

rolling reproduces this issue, i think we also can add test case with namespace as below. ```shell root@tomoyafujita:~/ros2_ws/colcon_ws# ros2 run action_tutorials_cpp fibonacci_action_server --ros-args -r __ns:=/demo root@tomoyafujita:~/ros2_ws/colcon_ws# ros2 action list /demo/fibonacci...
