In my view the linkage between the identity in From to domains authenticated

change that, it's not DMARC anymore.
It doesn't change that. It doesn't alter the current use of the From:
field.
Mediators might, and so far people have thought that acceptable.
My suggestion is that you offer some detailed analysis of current
security-related processing and specify how that will change to the worse.
The tendency for these topics is for people to make overly-terse,
overly-broad assertions and conclusions, without any of the detail that
permits validating the claim.
