I thought that's what the Return-Path: was for.
Ignoring the SPF hack/enhancement to use rfc5321.EHLO rather than rfc5321.MailFrom, SPF aligns with MailFrom.
Return-Path is an 822-level copy of MailFrom, created at delivery time. So, no, it no longer have a delegated address.
I understand that MLs want to field bounces so they can track and inhibit certain recipients, not to mention shield senders from (possibly very many) bounces in response to a single post. The vacation autoresponses alone can get very tedious very quickly. I'm not clear on how SPF alignment prevents this.
My observation about this imposing a rigidity for the MailFrom command was meant as a universal effect, not merely one relevant to list processing.
