"Do you care?" is a business decision. We care, but each has some limit to how much. Some of us may have implementations for which there is no business reason to add special-case logic for this case; some may have implementations that carry extra tables for this kind of thing and can easily add it; there may be some for whom it's important enough to add extra machinery just for that, though not likely many; nobody will care enough to go over the Internet updating every server and crawling content to identify candidates for re-tagging.

But we certainly do care enough to tell people in the first place *before* they tag their content that, if they want the most robust behavior, tag with "zh-Latn", not just "zh".
