As far as I can tell this is no longer actually used and its usage was removed in this commit:
83353ab9a6 (diff-a346bcfb05aab0cc0c0baa6018976f4efab339e8cade9f6f8fb658fcbd54ae2e)
Our systems are flagging this package as having a dependency on a package with a less permissive license so I would appreciate if it can be removed if its no longer needed. Let me know if that is not the case.
