sure, but i'm wondering why you throw *all* keyids, instead of only the
key-ids of the bcc'ed people?

right, but the sender can't know whether this is the case or not, i
think.

fwiw, i do agree with you that the onus is ultimately on the recipient's
MUA to fix this UI/UX disaster; but why force it on them in the case
where it doesn't actually eliminate any metadata leakage? (i.e., when
they're in To: or Cc: already, and not Bcc'ed)
