message processing hints allows to indicate that we wish a message not to be
stored in archive. The common use case is end 2 end encryption were there is
no sense for a server to keep it in archives.
But it's not clear if the hint is for the server or the destinee.
For instance, if Juliet doesn't trust her server or Romeo's server, she talk
to Romeo using whatever e2e encryption method, so she uses either no-store or
no-permanent-store hint to tell her server not to keep garbage data, but she
is fine that's Romeo's device keep history of the discussion.
But now Juliet want to send a password to Romeo, and she want to tell to
Romeo's client not to store the decypted message with the password, in order
to avoid anybody to read it in history if the device is stoled or whatever.
Is there a way to tell to server not to store the message, but to destinee's
device that it can store it, and to tell to server and destinee's device not
to store anything?
