So I guess it's this part of info.el that needs to become smarter:

              (when Info-hide-note-references
                (when (and (not (eq Info-hide-note-references 'hide))
                           (> (line-number-at-pos) 4)) ; Skip breadcrumbs
                  ;; *Note is often used where *note should have been
                  (goto-char start)
                  (skip-syntax-backward " ")
                  (when (memq (char-before) '(?\( ?\[ ?\{))
                    ;; Check whether the paren is preceded by
                    ;; an end of sentence
                    (skip-syntax-backward " ("))
                  (setq other-tag
                        (cond ((save-match-data (looking-back "\\(^\\| \\)see"
                                                              (- (point) 4)))
                               "")
                              ((save-match-data (looking-back "\\(^\\| \\)in"
                                                              (- (point) 3)))
                               "")
                              ((memq (char-before) '(nil ?\. ?! ??))
                               "See ")
                              ((save-match-data
                                 (save-excursion
                                   (search-forward "\n\n" start t)))
                               "See ")
                              (t "see "))))
