Then, a more natural way to achieve custom document-wide transcoder will
be introducing "org-data" transcoder into `org-export-transcoder':
(defun org-export-transcoder (blob info)
"Return appropriate transcoder for BLOB.
INFO is a plist containing export directives."
(let ((type (org-element-type blob)))
;; Return contents only for complete parse trees.
(if (eq type 'org-data) (lambda (_datum contents _info) contents) ; <=------------------
(let ((transcoder (cdr (assq type (plist-get info :translate-alist)))))
(and (functionp transcoder) transcoder)))))
For now, we have a hard-coded identity CONTENTS -> CONTENTS transcoder
when exporting the whole document, followed by applying inner/outer
templates. We may instead allow the export backends to introduce
"org-data" transcoder as a part of exporter definition. When non-nil, it
will be used instead of what you extracted into
`org-export-transcode-page'. And `org-export-transcode-page' will be
used as the fallback.
WDYT?

But your code ignores num:nil, does it not?
(defun org-export-numbered-headline-p (headline info)
"Return a non-nil value if HEADLINE element should be numbered.
INFO is a plist used as a communication channel."
(unless (org-not-nil (org-export-get-node-property :UNNUMBERED headline t))
(let ((sec-num (or (plist-get info :section-numbers)
(plist-get info :multipage))) ; <-- overrides num:nil
(level (org-export-get-relative-level headline info)))
(if (wholenump sec-num) (<= level sec-num) sec-num))))
