[num] syntax for footnotes is indeed a pain.  

However, the solution below is really a kludge because some parts of Org
(or external libraries) could hard-code it anyway.

>From an export perspective, you can turn these footnotes back into
regular text at the parse tree level:

--8<---------------cut here---------------start------------->8---
(defun my-ignore-false-footnotes (ast backend info)
  (org-element-map ast 'footnote-reference
    (lambda (f)
      (let ((label (org-element-property :label f)))
        (when (org-string-match-p "\\`[0-9]+\\'" label)
          (org-element-set-element
           f
           (concat "[" label "]"
                   (make-string (org-element-property :post-blank f) ?\s)))))))
  ast)

(add-to-list org-export-filter-parse-tree-functions #'my-ignore-false-footnotes)
