The motivation for this comes from JENKINS-36933 and JENKINS-37324.

I created a small plugin at https://github.com/vickychijwani/labelled-steps-plugin (see HOSTING-606) that works identically to the sh step but allows for a custom label by implementing argumentsToString(). Quick example:

labelledShell label: 'Building the universe from scratch...', script: """
    echo "Sparking the Big Bang..."
    echo "Cosmic inflation begins..."
    # ...
"""

Would the maintainers of workflow-durable-task-step-plugin be willing to accept the labelledShell step into the existing plugin instead? Or even accept a patch to the sh step with an optional label argument? That way we could avoid having a separate plugin for what seems like highly-requested functionality. Please let me know, thanks.
