Good point....

I personally don't mind auto ignore -- I even like the system yells about
those 3 files I forgot to add to ignore list every now and then (when the
mtime of the directory those are located changes). This is also something
different -- I can start keeping my drafts and spam directories alongside
other mail directories (or folders is you want to use that term).

Thanks for that id: it refers thread starting from id:"ylp7hi23mw8.fsf at tyndall.ie" 
( http://notmuchmail.org/pipermail/notmuch/2010/003145.html )

and the patch there is somewhat more complete (although old rebase-wise). 
It's easy to combine works together, but more difficult is to choose best 
terminology: database.exclude vs. new.ignore (or something in between or 
totally different). Ideas anyone?
