Yeah, I don’t think they belong in the spec itself either.

I also agree with your opposition to them; if anything, one
should filter the *output* of a Markdown-to-HTML conversion
so that it won’t matter whether people write literal `<em>`
tags or use asterisks. In both cases the resulting HTML is
benign, so why disallow those tags? OTOH disallowing literal
tags in the input means you cannot write a `<blockquote>`
with a `cite` attribute, since Markdown provides no syntax
for that. Scrubbing the input indiscriminately therefore
removes functionality for no benefit at all.
