Linting, refactoring and testing all have obvious benifits for anyone who has done any small to medium sized project and has had to rewrite and debug some amount of code, even if they don't know the concepts by name. Even version contolling is ubiquitous in almost any entry-level programming job, even if it wasn't before.
Most people who have made a website with CSS before would at best change the font size, the line spacing and the font face and tweak it to a point that feels easily readable and call it a day. Introducing variable widths between the characters of the font, digraphs and so on feels like more like exercising artisanship that only the experts would see value in rather than solving a technical problem.
Perhaps advanced web design/typesetting is the main application of this and it has a chance of inducing a better subconscious effect on the viewer. Sort of how magazines and books were designed back in the day I suppose.
