Increasingly they will find that their ability to deliver their mail to
many large mailbox providers (the Yahoo/Google initiative has now been
taken up by many others) will suffer -- particularly when spammers have
hijacked their domains or if they send from IP address ranges with a low
reputation

There is no provision in DKIM2 to not use DKIM2 (which seems kind of
obvious to me and I wonder why you ask)

the requirement is to publish a DKIM key -- which means, at its
simplest, that they need to be able to insert a CNAME into their DNS...
and (as is well-known) there is work elsewhere to try and work with
registrars to allow that type of activity to be outsourced to authorised
people (such as their ESP)

I would also note that some of the (mow many) participants in "Yahoogle"
do not set hard limits of 5K but "know a bulk sender when they see one"
and you will also find that some mailbox providers have requirements
that apply to all senders not just bulk senders.
