I'm not sure SPF is a good example.  While I'm sure *some* spammers 
actually thought in terms of "Hey, if I keep using fake addresses, some 
of them will have SPF records and get me blocked" or even "Whoa, these 
people are going to start blocking mail without SPF, I'd better add 
that!" I suspect most of it was due to the misconception that an SPF 
pass will get you through a filter.

I'm not saying the motivation won't be there, just that it won't be very 
strong when there's a guaranteed multi-year transition period in which 
the old standard will still get the mail through.
