No, in Git shallow threading means that all patches are sent as a
respose to the current cover letter, period.  It has nothing to do
with whether the current cover letter is sent as a reply to the cover
letter of the first or the previous version.

Deep threading means that every mail is a reply to the previous one.
Again, it has nothing to do with the relation of the current cover
letter and the previous cover letters.

Therefore, we do not recommend deep threading.
