The advantages you see are certainly real but they're not about interoperability. DMARC prevents a lot of mail from being delivered, the exact opposite of interoperating. In your case at least, there are good reasons to believe that the recipients wouldn't have wanted the mail, but that's a separate question. I also think that you're kind of an edge case, with a mail stream that you can characterize very exactly and a clear understanding of the costs of the mail that gets lost. People who know they have users on mailing lists and publish p=reject anyway, not so much. I'm with Scott, there's no question about the interop problem so document it and move on.
