I'm all for experimentation and being adaptive as new things come along, and I'm obviously supportive of the DMARC effort. That said, I hope that these are going to be configurable options, defaulted "off" for backward compatibility. This is because:

Current MM3 doesn't have a great way to expose plugin configuration options to the REST API, which is what a web ui would access to control this stuff. I've thought about it a lot, so I think I know how I'd do it, but there's details to be worked out and code to be written around this.

Mailman has support for anonymous lists, which can rewrite the From header to substitute the mailing list's posting address for the original author's address. I frankly don't know how much that feature is used in MM2.1, if at all.
