This protocol is used by applications that run outside the MTA to inspect SMTP events (CONNECT, DISCONNECT), SMTP commands (HELO, MAIL FROM, etc.) as well as mail content. All this happens before mail is queued.

Having yet another Postfix-specific version of all that software is a poor use of human and system resources.
