This is definitely one of those technologies that in theory looks weird and awkward, but in reality is actually super useful and productive. We've spent 10-15 years telling developers to keep style in CSS and structure in HTML. Which means the CSS/HTML mirror each other, Utility CSS breaks that paradigm and relegates CSS to a kind of Meta-customization, which you only delve into in 5-10% of the cases (e.g. to add a new custom colour or create a specific unsupported component).
