Ahh, yes.  I'd forgotten that as I wrap Mailman's wrapper in a larger
filter which does take and processes the envelope information.

However, there remains a distinct difference if several addresses are
conflated to the same POP/IMAP box.  In that case you lose the target
side of the envelope, and thus can't determine reliably which
Mailman-specific address/wrapper/alias to deliver the message to.

As of last I checked the Debian Exim packages ship with the
no-alias-file-required Mailman configs by default.
