That seems to be a major hurdle for this, unless every mail provider in
the world sets up an email verification service, sites will have to
maintain two code paths for email verification.
it also requires the user to be logged in to some kind of webmail
service for their email in the browser they are using, with
authentication handled by cookies, and for the verification site to be
the same domain/site as the webmail so that those cookies are sent. It
seems to require a lot of things to be just right to be as smooth as
envisioned.
(The spec could use more characters by the way, not everything needs to
be 3 letters long, kty, alg, typ, iat, cnf, jwp, iss, aud, evp, ...)

There's been some discussion recently on chromium-dev@ about a new
phone number verification mechanism using flash calls. I'm curious if
there's interest in expanding this work on email verification to
include both email addresses and phone numbers.
Unrelatedly, as someone who hosts their own email I'm curious if there
are reference implementations available for the email provider side of
this system. I'd love to play around with this API and want to be sure
it's not limited to users of the major email providers.

Specification
None
Summary
The EVP (email verification protocol) helps users create, access
and recover accounts by providing cryptographic proof that they
own an email address, rather than having to manually verify email
addresses with magic links.

Web Feature ID
Missing feature
Motivation
Verifying email addresses on the web today involves receiving
magic link and proving that you have access to the email inbox.
This is cumbersome for users and inefficient for developers:
emails can take a while to arrive, can get into SPAM folders and
users have to switch applications to verify them.
