There's no functional advantage. It does keep your initial tagging script
connected with notmuch new rather than offlinemap, if you ever need to run
notmuch new on its own.

If your tagging setup is really complicated, you could have some-tag in
new.tags config, and bail out early if notmuch count tag:some-tag outputs 0
(and obviously notmuch tag -some-tag tag:some-tag later in the script).
Just a thought.
