[css-ui-3] Clarifying if `cursor:pointer` is *exclusively* only for links

In recent discussions, people point to https://drafts.csswg.org/css-ui-3/#cursor (or the equivalent in older CSS specs) as evidence that cursor: pointer should only ever be used for links (in the context of opinionated articles such as https://medium.com/simple-human/buttons-shouldnt-have-a-hand-cursor-b11e99ca374b)

pointer
The cursor is a pointer that indicates a link.

It would be good to clarify if this is meant to mean it should only ever be used for links only (which I seriously doubt is the intention), or if that is given more as an example, e.g. "The cursor is a pointer that generally indicates a link. Often rendered as a hand with a pointing finger." just to soften the language and make clear that it's not making some sort of normative statement implying that it should never be used for other things / to give a more generic "this is clickable" visual hint (whether it's good/necessary or not is an argument left to the reader)

Start with the CSS UI Level 3 cursor section at the linked draft and review the definition of pointer in context. Check whether the wording is intended as an exclusive requirement or an example of common usage. Done means the specification's intent is clarified without leaving the question of permitted uses ambiguous.
