I don't think there's a better way, the results which the user is
viewing is the only visual reference for what the action they intend to
apply will use as the object of said action. I can imagine some people
wanting to have a way to apply an action to a live query string, but I
distinguish between these people and normal humans reading their email.
I expect that when a normal human is reading their email, they do not
intend to apply actions to messages as yet unseen.
I can see some people using the '*' notmuch emacs command as a very
interactive notmuch-poll.sh script. But I imagine the principle of
least surprise would be to have '*' only apply to visible messages, and
if the buffer is old, the buffer is the only record of what is being
viewed.
