I would argue that nowadays most dev workloads don’t break operating system. Most of the time I would rather have devs spending time to learn their database engine for back end. For front end devs would rather that they spend time understanding how web browsers work. While I like to spend time getting to know OS details and running windows or Linux servers - for instance I do get a grasp of CSS and can use dev tools in browser, but I see how a front end developer fixes CSS issues in 5 mins that take me 30mins. We cannot expect everyone to know everything - but also I think we can expect some basic knowledge of different parts of stack.
