No, I didn't. What some people (including to some extent you)
claimed is that knowing the language can be used to determine

What I said was that for most scripts, including some of those
written RTL, the list of languages using that script is essentially
open. I.e. I very much claim that I don't have such a correlation,
and I also claim that nobody else has such a correlation that is
complete. This prohibits implementation of generic language-to-direction
mappings that would be needed in browsers to be able to substitute
language information for explicit directionality information.

Regards,    Martin.
