Alex,

Looking at the Bimi technical details, one sees a mechanism to permit a 
standardized way of conveying a marketing image from its owner to a 
recipient, in aid of privileged display.  It is, therefore, simply a 
mechanism to increase marketing 'impressions'.

That some folk working on Bimi have a hope that its use will produce 
better adoption of some existing email authentication mechanisms is nice 
-- albeit, a fragile hope, in the absence of a demonstrated history of 
such an effort succeeding -- but it is outside of the technical and 
operational basics of Bimi. Adoption and use of Bimi can be 
significantly successful, in terms of facilitating marketing 
impressions, while having no meaningful effect on the global use of 
email authentication.

At the very least, that means the ranking order you have given is wrong.

But there also seems to be some indication that the fragile goal is 
being used to justify sub-optimal engineering design and to justify 
rejecting better design.
