It's my opinion of what Org mode _should_ do.

And it coincides with what other libraries do.  And it
fits what the manual suggests.

Your opinion is apparently that Emacs (in the Org-mode
doc) should recommend that users sacrifice those keys
to Org.  We disagree about that.

You want Emacs to (1) tell users that these keys are
reserved for them to bind, BUT also to (2) recommend
that if they use Org mode (which most users probably
do now) then they should bind them to Org commands.
I don't want Emacs to do #2.  #1 is good; #2 is bad,
and it, in effect, undercuts #1.

In my opinion no library should suggest that users
sacrifice their reserved keys for that library.
Users are free to do that, of course.  But it's
impolite, IMO, for a library to recommend that they
do so.

Users aren't stupid - they can figure out, if they
end up using some commands often, that they might
want to bind them to keys, including perhaps to
their reserved keys.  They don't need a library to
pitch them that idea.  And newbie users might well
get the wrong idea that they really need to follow
that suggestion or they could have a "bad experience".

Libraries that are purely 3rd-party can of course
do anything they like (not that they should, but
they can).

But I'd offer the same opinion for purely 3rd-party
libraries: Don't recommend that users globally bind
their reserved keys for your mode.

Org mode is not only a 3rd-party library.  It is
now part of GNU Emacs.  All the more reason to be
nice to users.

Very good.  Thank you for doing the right thing there.

Not good, IMHO.

And there is _no need_ to mention those keys.
It should be fine and enough to leave off the part
about ", like the ones reserved ... #+end_src."

That part's not needed for users to understand
that if they want global behavior then they can
bind global keys - which is the only message you
need to get across about those commands.

And, once again, those words shamefacedly suggest
that users use those keys.  Same problem.

Again:

Org is widely used.  Recommending that users use
those keys for Org is nearly tantamount to no
longer reserving them for users.  Not quite as bad
as actually binding them to Org commands on their
behalf (which would clearly contravene the guideline),
but almost as bad.

And totally unnecessary.

I'm on record, at least, as disagreeing with that.
One opinion.

Anyway, thank you for no longer having the rest of
the Org manual depend on the assumption that users
have sacrificed those keys to Org.

Perhaps someday someone else will finish the job by
removing the manual's suggestion that they should
make that sacrifice, "for a better experience".
