Arthur, would you be OK with adding a new CSS class to
<https://srfi.schemers.org/srfi.css> for links whose URL is shown in the document itself as the link text? I.e. something like:
<a class="url" href="https://example.com/foo">example.com/foo</a>
Whichever CSS class name and typography you prefer are fine. It could be in a monospace font, and CSS before and after pseudo-elements could be used to put angle brackets around the URL or something. But these are just suggestions.
a.eponymous {font-family: Monaco, Courier, monospace;overflow-wrap: break-word;word-break: break-all;word-wrap: break-word;}
