I don't think that's the root cause for why its never been considered a core skill and treated (when treated at all) as sort of an optional additional skill usually addressed, if at all, late in schooling as part of the English curriculum.

But I do think that's an additional challenge to getting it treated as a core focus in today's testing-obsessed public education context.
