I've been feeling a need for that recently, too.  While I
wouldn't mind moving away from procmail, this is its only
drawback for me.

Could a filter that decodes just the base64-encoded parts of
a message solve the problem?  It should be fairly simple,
esp. if it can rely on an existing decoder such as base64,
openssl, or MIME::Base64.  And if it doesn't worry about
signature verification.

I run a script that de-base64's text/plain parts of messages
so that I can grep them.  I invoke it manually after inc'ing
the message, but automatically decoding upstream would save
me a step.  It uses nmh programs (mhlist, and mhshow or
mhstore) so is too kludgy other than as a proof of concept
that maybe has been a bit too successful.

I agree with you and Ken that slocal isn't worth extending.
