+From my Reddit comment just now (the same point I've been aware of for a decade, but don't have in its own post anywhere; the "starting to look more like" phrasing may be new)—

+Consider an illustrative diagram in which there is a hard line in the combined height–weight configuration space, but the line isn't describable in terms of height or weight alone. If there were sufficiently many more traits/dimensions, we could imagine "not describable in terms of some small number of variables n" starting to look more like "not explicitly describable by humans."
