I don't think this is good enough, since I could have:

redirect "leg+cyrus at andrew.cmu.edu"

in my sieve script, which (if only the server name was included) would
then get dropped (or bounced or whatever).

However, putting the expected rcpt-to value in X-Sieve might be
interesting, since then we have a user and a host name that has already
seen the message.
