What about mailing lists that have different sender and

I know only two kinds of mailing lists, Sender = "Mail From"
and Errors-To = "Mail From", both with "Mail From" list owner.
What do you have in mind ?

Many lists use VERP, which modifies the return path depending on the
recipient of the message, so that the bounce handler can reliably
auto-unsubscribe broken recipients.

Errors-to is another name for return-path.

Please provide a precise reference to that prohibition.

Already discussed in mxcomp, e.g. in the thread starting with
<http://article.gmane.org/gmane.ietf.mxcomp/5453>

The forwarder would add its FQDN to the reverse path, and it
takes the resposibility for the delivery.

You misunderstand the SMTP meaning of "responsibility". It has nothing to
do with who receives error messages: it means that the responsible host
must not silently lose the message in case of failure. See RFC 1123
section 5.3.3.
