Comment 6 for bug 141157

I think writing "${lpuser}@bazaar.launchpad.net" in the lock would be confusing.

Normally, the bzr committer id includes a REAL user-provided email address that can be used to contact a human. We should not generate fake email addresses like this.

We should use the "${user.displayname} <${user.prefferred_email}>" if the email is public to authed users on the website, or use "${user.displayname] (${user.name})" or, if it exists, use some @launchpad.net email alias that redirects to the preferred of the user.
