It has been.
However, part of the problem lies in the bibtex-map-entries:

          ;; If we have invalid entries, ensure that we have forward
          ;; progress so that we don't infloop.
          (if (= (point) prev)
              (forward-line 1)

The code above always skips a bibtex entry starting at bob.
Hence, the provided example bibliography is parsed as empty, which is
not expected by Org.

While handling empty bibfiles should be fixed on Org side, the current
behaviour of bibtex-map-entries should indeed be fixed on Emacs side.

Best,
Ihor
