I like your workflow very much. 

Do you think this could be done directly in a SIEVE script ? The more I
use notmuch, the more I think many things could be done directly at the
IMAP/SIEVE stage. Am I alone thinking this way ? I mean, today, I put
things in specific folders, etc. Notmuch is almost exclusively used with
search phrases like: folder:notmuch and tag:unread.

I am not SIEVE expert but I am pretty sure it can do way more things
than just dispatch messages into folders.
