I do not know of any situation in which DMARC adoption would improve deliverability, and most people that configure it are just engaging in cargo cult sysadmining. DMARC with p=reject is useful when the sender domain is a phishing victim, e.g. a financial organization, but most users do not need it.
In other words: if these people want to support use cases like forwarding and participating to mailing lists then they should adopt DKIM and ignore DMARC. -- ciao, Marco
