Thanks. I'd find this useful as well.

Fwiw that's what Emacs's lisp/calendar/timeclock.el does:
(defun timeclock-query-out ()
"Ask the user whether to clock out.
This is a useful function for adding to `kill-emacs-query-functions'."
(and (equal (car timeclock-last-event) "i")
(y-or-n-p "You're currently clocking time, clock out? ")
(timeclock-out))
;; Unconditionally return t for `kill-emacs-query-functions'.
t)

Dropping the duplicate definitions using an alias sounds good, though as
I mention below I'd prefer the spots that are specifically concerned
with a buffer to keep using the org-clocking-buffer name.

Hmm, this patch doesn't apply to the current master (041459727). The
preimage blob is quite old:
$ git describe 892ae1810
release_8.2.7b-7-gbacfe5b4f:lisp/org-clock.el

Eh, so this too could just be an alias to org-clock-is-active, or, if it
looks like any callers really depend on this being t rather than just
non-nil (but why would they?), `(and (org-clock-is-active) t)' would be
better. Anyway, I know you're just doing the plain substitution here,
so I'm fine keeping it at that.

This is an example of a spot that I think should continue using the
org-clocking-buffer variant for readability. And scanning the other
spots in this patch, I think they actually all fall into this category.

Hmm, why use org-clocking-buffer rather than org-clock-is-active? After
a patch that introduced org-clock-is-active and switched a bunch of
spots over to it, I would have expected you to use it here.

lisp/calendar/timeclock.el has the following option:
(defcustom timeclock-ask-before-exiting t
"If non-nil, ask if the user wants to clock out before exiting Emacs.
This variable only has effect if set with \\[customize]."
:set (lambda (symbol value)
(if value
(add-hook 'kill-emacs-query-functions #'timeclock-query-out)
(remove-hook 'kill-emacs-query-functions #'timeclock-query-out))
(set symbol value))
:type 'boolean)
I wonder if we should do something similar.
