cool, thx for the suggestion.

the "notmuch search" part of the pipeline alone takes ~19s (wall time,
and actual CPU time) for me though :/  It returns 30504 threads!  how
many threads do you get?

you're effectively re-tagging every single message in every participated
thread every time you run "notmuch new", right?

I like this outcome!  I'm just looking for a way to do it that wouldn't
cost me so many cycles -- Maybe if i only run "notmuch new" once a day
:)
