Every tool has limitations.An 18-wheeler truck is not broken or immature because it fails to corner like a Maserati. A Maserati is not broken or immature because it does not have the carrying capacity of an 18-wheeler.
DMARC was designed to handle a particular usage scenario and its limitations have been carefully documented.
Or perhaps we need to declare email broken and immature because it does not (yet) satisfy a long list of entirely reasonable functional requirements, such as, ummm, author authentication?
Long deployment and use and deep knowledge don't matter; only satisfying someone's list of requirements does?
