You've said it, but not really explained why. Sure, you've pointed
out the case where a registry wants to use it for authentication,
but it _can't_ be used for that purpose today anyway - it tells you
nothing about the authenticity or even identity of the true sender.

I'm interested in a well thought out argument against encoding
additional sender information into the envelope sender like VERP
mechanisms do, and not a hand waving "its broken" statement.
