I was under the impression that your main interest in p-i was the easy
addressability and availability of raw emails, for use such as with
git-am.  Are there other users pining for this kind of thing?

You are expecting people to use the xapian query language for this
stuff?  Mailman offers that style of click-click browsing already.

No, postfix already spam checks everything upon receipt, before delivery.

This shouldn't be something that we need to write code to do, if it needs
to be done at all.

It must be some mailman administrative script.  Just crontab another

The proposal is to not touch /etc/aliases* NOR /etc/mailman/aliases*.
The proposal is to generate a new file like
/etc/postfix/mailman-inbox-aliases from /etc/mailman/aliases.  That
new file would be the one postfix would read.  It could be texthash:
rather than hash: so postmap would not even be necessary for updates.
That depends on whether the relevant alias-expansion postfix process
is short- or long-lived.
