While the slug helps someone know what they're opening before reading it, most apps have link previews which give you just enough information you need.
Maybe on some sites it's fine but I feel like link previews need more modularity on size or something. Perbaps even configurable both host and client
The information density of the preview has to match, if not exceed, that of the context in which it is provided. Most of the times it's a placeholder image with less text than the URL itself.
