AFAIK they should not be globally routable and they are only for internal usage of the exchange points.
Very bad idea. 1) When you traceroute through an exchange point, the IP addresses you get should be routable, for easier debugging. 2) Path MTU discovery may depend on it. Having IXP addresses not globally routable is as wrong as having RFC 1918 (or FECO::) addresses at an IXP.
