It's trivial to extend the example to take this into account. E.g.:

    :lang(ja) { writing-mode: tb-rl }
    :lang(ja) table { writing-mode: lr-tb }
    :lang(en) { writing-mode: lr-tb }

This would allow you to express your preferences for writing
directions, if not provide graceful degradation in all cases.

I think you're underestimating your peers in this forum.

That's good to know.

I think you're disregarding other proposals too quickly, with too
strong words, before the proposals have been developed. 

All proposals needs discussion and development, that's what this list
is for.
