org-add-note puts a '\\' at the end of the first line. Is it expected
the user will put '\\' at the end of each line of a multiline note
(except the last line)? Why is this done?

No.

To prevent fill-region from concatenating the auto-generated text in the
first line and the user input in the following lines.

Ah. Is that mentioned somewhere in the Org manual? I don't mean the
details of filll-region, but a little something to answer "why is that
there?" by new users.

Hmm. Not quite as it doesn't say anything about Org notes.

No, AFAIK, the exact format of notes is not described in the manual.
We do not describe every single detail in the manual.
I believe that the exact wording of the notes is not something we have
to describe.

Hmm. glancing through the manual, there is a bit of assumption implicit
about the use of '\\'. We had the problem with Unix Shell scripts that
we would need a backslash at the end of a line to prevent the EOL as
being interpreted as end-of-input. Depending on the layers of scripting
we were using, we added backslashes after the backslash because each
layer would peel off a backslash. This is what I first thought of in
reading the manual.
Seeing '\\' at the end of the note line, I thought something would get
messed up if the EOLs (except last) in the Note were treated as
end-of-input, so I added them to all but the last line. This is what I
think needs clarification.

We do document the line breaks in

The only thing I see with respect to '\\' is:
Paragraphs are separated by at least one empty line. If you need to
enforce a line break within a paragraph, use ‘\\’ at the end of a line.
Which doesn't answer the question of why org-add-note (etc) added it the
end of the first line of a Note which lead to my confusion. It's easy to
assume, if Org is adding '\\' to the first line of the Note and the Note
is a unit, then this is there to prevent folding/wrapping in the Note
when Org does "something" (but what?).

Line break is a "forced" break of a line in paragraph. When there is a
line break, paragraph does not re-flow to the page width.
Re-flow may imply different things, including `fill-region' command in
Emacs or paragraph layout during export.
The detailed reason why we use this particular markup is that
otherwise some internal code assumptions inside Org mode may break when
users run `fill-region' on the notes. This is an internal implementation
detail which should not be explained in the manual.
What we might explain better is what is a line break, although I am not
very sure what to explain here - I may be too familiar with the concept
from my LaTeX-foo.

Hmm. Fill-region will also compress the blanks in the generate note
header -- does that run up against the code assumptions?
I'm all for keeping internal implementation details out of the user's
manual, unless...

The manual should set expectations on what an Org file should look like
-- at least the key components. It already defines Header, Paragraph
and Timestamp. What I think is missing here is the definition of a Note
along with some structure info about it (header line + 2 space indented
paragraphs[s]) to prepare the user. In this, I probably come from a
more Reference Manual viewpoint (ie. "this is what all the pieces could
look like -- now lets discuss why you want each piece"). You could say
that the '\\' is needed to keep "other things" from combining the header
and paragraph of the note. You could leave the details of "other
things" to variable or function docstrings as well as internal code.
p.s. would requiring a blank line after the Note header eliminate the
need for '\\' ?

Unlike headings, paragraphs, and timestamps, notes are not a part of Org
syntax. Their format is customizeable via `org-log-note-headings'.
However, it is probably worth describing the notes in 5.3 Progress
Logging section of the manual.

I am not sure if I understand what you mean here.

Hmm. The docstring on that should discuss what it's looking for to say
"this is the end of the state notes". Does a plain note (org-add-note)
count as a state note?

Oh! That's an interesting point. That variable is not mentioned in the
Manual (AFAICS), but perhaps it should be -- particularly around the
talk of "rescheduling" (and "delschedule" which I don't see in the
manual). Mentioned only in the sense of, if you want to change the note
header, look here.

I'd agree. In particular, what depends on the format of the note
(header) -- like Agenda. To warn people what they can or cannot touch.

Yes, it does.
I tried to improve a docstring a little on main.
