IX's are not, alas, the center of the internet, no matter what anybody's
marketing might say.  the vast majority of traffic exchange is by private
interconnect, which might be an IX crossconnect, but might just as likely
be some kind of ISO-L1 or ISO-L2 link through a metro or telco or whatever.

there is no justification for making an IX into an address allocator or
address aggregator, unless it's an ISO-L3 IX with regulatory powers, which
isn't the norm in most places around the world, and isn't likely to become
such, even if it were uncontroversial, which it also isn't.
