Okay, today I did some research and found that every "C-c
C-<letter>" binding is used in Org Mode except for "C-c C-g".
While that one is technically reserved for the mode's use, I
suspect the reason it's unbound is that people are accustomed to
using C-g as a quit command (and they get that effect if they
accidentally type C-c, because then they type C-g and it's just an
undefined key -- i.e., it quits, which is what the user wanted).
Note that while "C-c C-h" does not appear to be bound, it actually
is: it gets you a help buffer about the Org Mode keybindings
(which then, ironically, does not list "C-c C-h" as one of the
bindings).
(It's not clear to me whether Emacs's conventions consider "C-c
C-i" to be a letter or whether they treat "C-i" as "TAB" and
consider it special; based on the previous evidence in this
thread, maybe the latter, so we shouldn't consider "C-c C-i" to be
available.)
I think what this is telling me is that Org Mode keybinding real
estate is quite valuable :-), and that unless there are other
people who feel as strongly as I do that `org-fold-hide-subtree'
is amazingly useful, we probably won't decide to bind it by
default in Org Mode. So I should just continue to bind it to a
custom key myself and continue to live a glorious life all alone
in my private keymap splendour.

So FWIW C-<tab> is not bound in Org Mode buffers for me, in=20
Emacs
30.x (i.e., recent development builds).
lisp/tab-bar.el:130: (unless (global-key-binding [(control=20

lisp/tab-bar.el:131: (global-set-key [(control tab)]=20

Minibuffer file cache completion should not be relevant to
Org=20
buffers.
Ah, I don't use tab-bar at all (at least not as far as I know),
so=20
I'm not 100% sure what the above is saying.
Are you saying that the only current default binding for
C-<tab>=20
in Emacs is that one in tab-bar.el, and therefore we should
feel=20
free to rebind it in Org Mode? If so, we should still be=20
cautious, since Emacs has policies for maintaining the
keybinding=20
space. Generally, the space "C-c C-<LETTER>" is reserved for=20
major modes, so ideally we should find something in there if
we=20
can -- although Org Mode has used up a lot of that space
already=20
:-), so I'm not sure what's left, unless we decide to swap out=20
some existing binding in favor of this one.
(I realize this contradicts what I said in my inital post. I
had=20
forgotten that C-<tab> was not part of the mode-reserved space.)
