The subject of the thread is the Web Animations JS API, not CSS.

(But there's nothing wrong with putting strings like that in CSS; I'm
unsure why you think there's a meaningful difference between <path
d="giant string"> and <path style="d: 'giant string'">.)

A <path> carries no intrinsic meaning, just like an <img>; it is
completely opaque to a search engine, screen-reader, or other
machines.  It is entirely unlike text content.
