I basically agree. However, the proposed mapping between SEXP movement
commands in programming modes and in org-mode seems rather loose:

Presumably the intended mapping is

C-c C-n <--> C-M-n   "n command"
C-c C-f <--> C-M-f   "f command"

That suggests that the n command in Org-mode should skip over the next
subtree, like forward-list; however, it advances over a body to the
start of the next subtree.

In fact, isn't there an argument that the Org bindings are the wrong way
round?  If we define in Org-mode:

- atom :: the body of a heading
- SEXP :: an atom, or a subtree

then the n command in Org-mode currently behaves a bit like forward-sexp
(C-M-f) , whereas the f command in Org-mode behaves a bit like
forward-list (C-M-n).
