I agree about year, title, and date. However, not the code. I'd expect
code snippets to use LTR by default. Maybe with an export flag to switch
to RTL.

Should we allow #+language to have multiple values like

#+language: es en ru uk

with first value defining primary language and the rest being secondary?

Also, what does bidi=basic do?

Finally, may it be useful to provide a syntax (affiliated keyword) that
will set a language for specific paragraph?

Do we have #+FONTS setting? I'd say that it is worth adding.
