With the impending closure of the NSFNET Backbone, and the distfribution of those funds to (academic) regional networks for the purpose of buying backbone service from ISPs on the open market, NSF feared that universal connectivity within the US higher education community might be lost - if all ISPs concerned did not peer with one another.
The NSF never required ISPs peer with one another. The requirement was to "connect" to the three primary NAPs, not exchange traffic. Universal connectivity was an issue we are still dealing with.
Accordingly, NSF established the NAPs as open exchange points, and the funds distributed to regional networks to buy backbone service had a string attached: the regionals could only buy from ISPs who agreed to come to one or more NAPs and exchange higher ed traffic. Thus the universal connectivity of the community NSF was charged to serve was aassured.
The CIX router had a mandatory peering policy, assuring universal connectivity among its members. For several years, the CIX router served as the "router of last resort." But some providers didn't like that policy. Neither MAE-East, or the NAPs had "AUPs" covering traffic exchange.
NSF never intended the NAPs to be the ONLY peering/exchange points, and never contemplated a 'stamp of approval' (or disapproval, for that matter) for anybody else's exchange point; the NAPs were inclusive, not exclusive.
