I don’t see them as scroll bar replicas; good ones are very narrow but high contrast, to easily offer a compact visual sense of article length – rather than page length, an important distinction when there are cited sources, recommended articles, and a footer menu. Different functions.
IMO, they should coexist with a well-designed vertical scroll bar.
In brass fittings and brass spigots, for one.
And lots of weird/toxic shit in hoses that isn’t lead (like plasticizers etc), because of the manufacturing process. And because hoses aren’t by default regulated for Safe Water standards.
