That is an interesting view. I can accomplish the same by using
sub-domains in d= instead. Are you simpy going to strip
sub-domains from d= too?

It is interesting that receivers (Hotmail/AOL/Yahoo) suggest to senders
to separate their different type of mail streams
(transactional,marketing,etc) by using IPs. The same can be
accomplished with DKIM and i=.

I also hadn't realized that DKIM was strictly meant to benefit
receivers.
