A plumbers' work basically always improves society. A software developers' work sometimes improves society, sometimes harms society, and sometimes is a meaningless waste of time. Society encourages developers to use their judgement and ideally improve society. At it's core, I think caring about the feature you're making is a judgement on whether you think the feature will improve the world or not.
