Exactly. The Web is a medium with built-in customizability. This "our product is perfect and must be used as is" attitude reminds me of a relatively recent example that seems to be dying down: mobile websites that used the `maximum-scale=1 ` value in `<meta name="viewport"`. This disabled zooming in mobile devices. This was an accessibility issue that affected people who otherwise don't encounter other accessibility issues. If it were simply a matter of providing the smallest payload to clients, these sites could provide some sort of external manifest/source map mapping human-readable class names to hashes.
