No my concern is that something simple as the numbers should be done
correctly by deafult without further attempt. If it was TeX, I would say it
is macropackage's job to fix these.

LuaTeX's claims to be the engine that supports Arabic, Right?
My concers has not got anything to do anything with plain, LaTeX, ConTeXt

I do not think he cares at all.
My point eventually is something as basic and elementary as numbers should
be done correctly by default and if you guys want to ignore the issue, that
is fine. But you can not change facts.
