My understanding is that we have received some comments so far against Virtual DMARC.
The main comments are as follows: - DKIM has opt-in nature. - DMARC is composed by policy and reporting, but Virtual DMARC does not have reporting. - Receivers can work this kind of operations using logs as they like.

In such case, dmarc=pass will be issued for any DMARC record where "strict" decision policy is set.
