As I recall the IERS was asked a while ago, with no definite response yet.

French copyright law is a funny thing, not to mention international bureaucracy, 
and it's possible we'll be stuck with using a non-IERS file indefinitely. I hope 
the NIST can maintain a leap-second file in a timely fashion; otherwise we'd 
have to do it ourselves, and then the world might have *three* files where one 
should suffice....
