May I suggest to provide a 'convenience' launchfile, `ur10_joint_limited_bringup.launch`, which sets this argument to `true`, so users can load that directly? Ideally, the name is identical to the corresponding urdf / xacro.

In my experience users have trouble finding launchfile parameters, even if they are documented well. Providing the launchfile would make it show up immediately when they try to tab-complete.
