I like this idea. But IMO we should avoid another call to notmuch count. Notmuch-hello buffer already displays the message count on the first line. I would propose to implement this functionality not as a hook but as part of the section which outputs the first line. We can add an option to disable it if you prefer but I do not think it is needed. This is less flexible than a hook, but IMO it is not a big issue.
