No, this is clearly a bug and you have got to fix that. Things are supposed
to work in the general way, if "r" stands for right alignment, whether you
are doing RTL or LTR it should mean the same thing, you can not just
consider yourself and ignore the rest of people. Also it looks really funny
to say "I simply swap the meaning of r and l in my head".

If you want to do proper bidi implementation as done in bidi package, you
have got to deal with these. Of course tabular is a very small example.
