ROS2 Humble "topic echo --once --flow-style" in Galactic?
I've been using ROS2 Humble for a few weeks and have really become attached to the new "ros2 topic echo --once --flow-style /
I'm setting up a Galactic environment to work with the new TurtleBot 4 Lite, and am going to miss these topic echo options immensely.
Is there a way to "back port" these functionalities to my Galactic workspace?

You could always try building the
humblebranch of ros2/ros2cli from source in your workspace.No guarantees it'll work though, as those features -- or others -- could depend on functionality in other packages which is only available in Humble.

@gvdhoorn - True - beyond abilities/focus right now, and I don't want the runtime exceptions that came with running my works-fine-in-Galactic nodes in Humble. (They added a need to catch ExternalShutdownException and sometimes even that didn't prevent exceptions when shutting down multiple nodes in the same package.)
