Large ISPs/ESPs like DMARC because they, by definition, are too-big-to-block so they can afford to offload the support costs of DMARC failure cases on the small email operators. There where they happen not to be too-big-to-block, those ISPs/ESPs don't dare to indulge in such practices (confront yahoo.com vs yahoo.fr/yahoo.es DMARC policies). They way for small email operators to "work with/around" that, is to not check DMARC for incoming email, to publish at most a DMARC policy of "none", and to stick to good old plain-SPF.
