To me it’s not so much the company can’t delegate authentication - it’s how

hard, not it’s challenging, but simply … can’t. They cannot sign with foreign
DKIM domains, and they cannot support different domains for SPF authentication.
Should DMARCbis make the recommendation that if you are providing mail services
that you SHOULD be able to support corporate customers using DMARC?
IMHO at least an appendix should say that if you can't do anything better you
have to rewrite From: with examples of legitimate display-phrase, expanding a
bit the first bullet in Section 11.4. That can also be a good place to explain
the kind of damage DMARC causes.
