Since the same origin policy is the primary meaningful security boundary
on the Web, I expect for most people interested in security and privacy
that emails that dismiss SOP are generally put in the spam folder.

I do understand some people are interested in creating, for example,
'unique identifier' across all websites such as in the form of a X.509
certificate. These sort of  totalitarian identity scheme (often based on
broken crypto, such as <keygen>) will likely implemented across all
browsers, as would any payment scheme that makes the same broken
assumptions. Supporters of such positions seem to have a lack of
understanding of the modern Web and/or basic cryptography and while to
some extent basic education can be done on Web-related mailing lists, I
doubt many people find it is a productive use of their time given the
large amount of high quality online courses out there and relatively
important work that has to be done in terms of Web standards.

In particular, it is likely more productive for various non-SOP schemes
to find a way to adopt to SOP in a principled manner and so maintain
security and privacy properties. Payment schemes, identity schemes, and
the rest should and can do this.
