For all the reasons why Reply-To Munging Considered Harmful.

Obfuscation is a minor annoyance, but concealment is problematic in
cases where the email is the identity, eg, matching list posts to
issue tracker IDs.

For example, I signed up for and log in to Launchpad as
"stephen at xemacs.org", but I have to tell bzr that my ID is
"stephen-xemacs".  Wow, that's transparent.  But at least it's
guessable.  Getting from "Stephen J. Turnbull <email concealed>" to
"stephen-xemacs" is not going to be easy if you don't already know me.
