Sure. One could do this. But I don't see the point of encrypting an
individual copy for each To/Cc recipient. The only additional
information a single message encrypted for all To/Cc recipients gives
the recipients is the list of key IDs of the other recipients. Under
very special circumstances this could be undesirable, but under those
special circumstances one probably also doesn't want to have all
recipients listed in To/Cc. So, we are back to using Bcc or sending
completely indiviual messages.
