I found your link interesting and informative. I'm curious if you have any specific comments on this quote from the story:

> From there, the email services which implement MX2 would publish a public date, on which all messages sent to them by the old MX record, will be automatically sent to Junk. If just Microsoft and Google alone agreed on such a date, that would be 40% of global email traffic.

Do you think this change wouldn't be enough? If so, why not?
