Mailman already does this for the archives, at least for a plain text
message body, but not for scrubbed attachments. Do you see cases where
this isn't done?

Neither Mailman nor the MTA can do this for messages to be sent. The
message part is base64 encoded in the first place because it contains or
could contain non-ascii characters (utf-8 in your example fragment)
which can't be included in message parts "on the wire" if the message is
going to be acceptable to all MTAs.

Plus, such recoding would just add one more way in which Mailman would
break DKIM or PGP signatures.
