"NoRecipientAction=action" option is designed to handle problems with
some broken MUA's (of which there are quite a few). Postfix does this
out of the box. I'm not sure why Sendmail doesn't.

The design is to add a valid header into the email for processing by
some other application or milter. One thing it can do is grab the
envelop sender and add that as a To: field inside the email.

Did you restart Sendmail after rebuilding the Sendmail.cf file?  Other
than that, you might want to file a bug (or see if it's already filed). 
I'm sure this feature is not well used (though it would have come in
handy for some earlier versions of Mailman!).

Well, this is quite simply an illegal format for an email address.
