My conclusion (it won't surprise you to learn) from this thread is precisely the opposite. In theory, DKIM is enough for DMARC (this was always true), but in practice it is not. I don't think there's evidence of a systemic weakness in the protocol. We've seen evidence of poor deployment of the protocol for SPF, but I think the solution is to fix that (see the separate thread on data hygiene).
