Indeed. With this approach, you would also be able to avoid having to
redistribute the IX LAN prefix into your internal network from your
border routers. :)

Avoiding redistribution of the IX Local Area Network prefix _into_
your network also lessens the chance of accidentally leaking the IX
LAN prefix into the DFZ with your Autonomous System Number as the
origin of a potentially invalid (IX LAN) prefix announcement.
