This option seems like the type of thing that would be used primarily
by frontends, so it matters much more that they have control over the
output than that the command line is terse.  We should provide
reasonable defaults for the occasional flesh and blood call to the
CLI, but I don't think we need to cater to that use.

This would make a lot of sense in the frontend configuration (so much
so that we already have it!  But it's currently limited to removing
headers).  Also, if it's in the notmuch configuration, then when
programs do need the headers to do something, it becomes very
difficult to request what they need.
