Short answer, no.

I'm afraid we don't have any documentation describing the split between
the library and the cli, apart from the library API. IIUC the history is
that it was originally all lumped together, and then the library was
abstracted as a toolbox for creating email programs on top. The cli
could be considered one such email program (and notmuch-emacs builds on
top of the cli).

I don't think the notmuch new command would be a good fit in the
library. It has too much application level policy that doesn't belong in
the library. That said, I could imagine coming up with another, higher
level library consisting of the main building blocks of the cli, and
having bindings to that. It's just that it's a non-trivial amount of
work, requiring a significant programming *and* review effort.
