As I said in my reply to Drew, this is what I call a "cheatsheet" :)

I have no complaint about C-h m, C-h b, C-c C-h, as long as I need them
"rarely", as you say.  When reading an outline, I _frequently_ open and
close headings.

A fair point, though correct me if I'm wrong, but it does not look like
we indent NEWS entries?

org-mode has a few ways to work around this conflict:

- TAB on an "empty" heading (e.g. right after one inserts a heading)
  cycles through section levels (by adding/removing asterisks),

- If org-indent-mode is nil, sections bodies are "hard-indented"; TAB on
  section bodies indents them to (1+ section-level), C-j auto-indents
  new lines.

  (Frustratingly, org-mode uses what I think of as the "old" convention
  to use RET as "plain newline" and C-j as "smart newline with indent".)

- If org-indent-mode is t, bodies are "soft-indented" (with line-prefix
  and wrap-prefix).

Any of these could be useful additions to outline-mode IMO.

By default, org-mode only shows top-level section headings; subheadings
and bodies are elided.  The ellipsis is a visual cue that there are
things to expand.

Once the non-specialist user has this "EXPAND-ME" cue, admittedly they
still need to learn the binding.  Luckily with org-mode, there's just
one: TAB.

I wish I could reply "well obviously the non-specialist user will just
click on the heading and voilà!", but it looks like one needs to
(require 'org-mouse) first.  Ah well.  No reason this couldn't be
enabled by default in outline-mode.

Right, let me qualify this better:

- There are 11 commands with bindings for selecive display in
  outline-mode (5 show, 6 hide).

- There is only 1 command I care about for selective display in
  org-mode: TAB.

No argument there; I'm not advocating for using org-mode with NEWS.

Though for all of org-mode's complexity, I have yet to see an Org file
where "mindlessly hitting TAB" does not show/hide the heading at point
(… as long as point is on a heading).
