@christophebedard I see the convenience BUT is it necessary? Most ROS arguments can be given in an idiomatic way (e.g. via remappings) already. If we need --log-level, I'd argue we should add it. CC @wjwwood @ivanpauno.

I found #60 while answering an answers.ros.org question: https://answers.ros.org/question/380883/specify-log-level-on-ros2-node-in-launch-file/#380965. In this case, it seemed to confuse the person. They weren't sure whether they needed to use -- beause launch_ros appends --ros-args ... too (even if in practice rcl handles it just fine). I think having ros_arguments would make it much simpler, but yeah it's up to you the maintainers 😝
If we need
--log-level
you mean like a LogLevel substitution?

I see. I was wondering about the use case. If not having to write out --ros-args helps people, I'm onboard.

Like a log_level argument that can be a substitution. But that's a separate PR.

Seems like we can handle things better if the user explicitly tells us when something is a ros argument, so +1 from me.
