Actually, It's worse. There is three[1] slightly diffrent proposals at the moment. 
There is work going on merging these proposals, so it definetly too early to
adopt these proposals.

The implementation in majos SMTP servers isn't that large problem, most
mailers are modular enough these days to handle the problem with an
external module.

And I think you didn't read the proposals and the discussion related to them
at all.

First hint: envelope from vs "^From: "

Second hint: If you insist on your right to forge your email address, 
anyone else can forge your address as well. Is that a right you really
need?

Third hint: You can still choose to allow any IP send emails in your
domains name. Just do not add the records in dns, and everything will
stay as it is currently.

The antipathy against the a POSSIBILITY of a domain owner to restrict
sending mail in name of his own domain to few IP's is what is silly,
not the proposal...

and most non-technical users will probably have one address and one
SMPT AUTH based mail server to use.
