Description

Just a bit of syntactic sugar to make it easier to use boolean launch arguments. It tidies up launch files and avoids capitalization errors like

[ERROR] [launch.actions.declare_launch_argument]: Argument "use_rviz" provided value "True" is not valid. Valid options are: ['true', 'false']

Is this user-facing behavior change?

Yes, it adds a new shortcut.

Did you use Generative AI?

No.
