exactly. and as some people in this list already pointed out: it is not.
i don't like people to enforce their "strict" policies on me, unless these 
strict policies are legal. what's next? everybody needs to run an ident 
daemon on his mail server ?

if you want to help your customers getting rid of their spam, why not force 
them to use a spam filter? oh, i forgot.. they pay you and we don't.
it's pretty obvious, that as long as the reverse dns isn't in RFC, chances are 
that the good guys send mail from servers without reverse dns. => if you 
don't accept mail from them, your customers will lose "ham" mail.
