No, you can not expect evveryone to think like you. I guess that would not
be really fair.

Maybe easier, but it would be full of mistakes and ignoring RTL
typographical conventions. Proper bidi implementation is not easy, this is
something I said in the first place, doing things consistently costs time,
energy and testing.

Persian is a vital part of RTL. Any RTL implementation, should respect all
RTL scripts. Let's not ignore the fact that Persian and Persians have had a
lot of influence on science, and the language. Khawarazmi (a Persian
mathematician) was the father of algebra, the word algorithm is the
latinisation of his name, something that enabeled Knuth to make TeX.
