I do this inadvertently now. I send through TMDA, which makes a separate message for each recipient for its own reasons.
The only time hashcash-sendmail "forks" a message this way is when there's an

their own copies so that their identities are not leaked (via the X-Hashcash
header) to the other (public) recipients.
