I don't know anybody who regularly retro-mods their archives for
reasons of taste, but on the Mailman lists "how do I get this hazmat
out of my archive" is a FAQ. It's a little inconvenient, but could
easily be applied to retro-modding.
Why? GDPR, for the obvious hors d'oeuvre. Then there's the
occasional spam that makes it through. And unwary admins who strip
and store attachments frequently later discover they contain malware
or caches of stolen credentials, etc. If you allow download of mbox
archives, stolen credentials can be hidden in message header fields
that the web interface and user MUAs don't display.
