This is what I do because my sites aren't complicated enough to warrant a build system. Personally I think most websites out there are over-engineered. Example: a Discord friend made a React site that displays stats from a gaming server. It looks nice, but you literally can't hyperlink to any of the data, it can only be loaded dynamically and only looks coherent on a phone in portrait mode. There are a lot of people following trends (some good trends) but without really thinking about why.
