Do you have a setting to change From: user@domain to From: user@domain.INVALID - that is the hack I would like to use.
No, not currently. It is an interesting idea, but it may cause issues in delivery of mail From: a non-existent domain.
None of the current options to try to work around the DMARC breakage work well; all fail in various ways.
Until people figure out real ways of making DMARC work with forwrders & mailing lists (see ietf-822@ietf.org for one place discussions are going on), I think it useful to have more work-around hacks out there so that people can experiment with them to see which ones more-or-less work in different situations.
