High-capacity attachment at large Internet exchange points would traditionally be done on a device capable of absorbing the fully available selection of routes. Not only is that not necessary, but for some kinds of applications (CDNs), nameservers, many classes of server, or extensions of existing networks, very minimal FIB routes are required on a switch or router. This provides an opportunity for reduced attachment cost, as well as minimal threat of obsolescence due to table size.
