Poor choice of wording.

If I was implementing this, I would assume that any packet with a
non-zero value is illegal by this RFC, and act accordingly.

I would assume that this "future use" may require handling of the
packet in a non-standard way, and packets with a non-zero value cannot
be used until the "future use" is better defined.

Also, the above statement should really clarify how routers should
cope if they receive a non-zero value. Drop it, pass it through
unchanged, or set it to zero?
