I generally agree with this, although I'd make the minimum /27. There's no need to assign a /24 to something that neither requires that many IP addresses nor requires global routability, and there are private interconnects with a small number of participants that would benefit from addresses guaranteed to be unique.

I vehemently disagree with this. Expecting to -eventually- have more than 126 participants should be more than adequate to justify a /24 for an IXP. IPv4 addresses are not so unobtainable that we need to force IXPs into a regime where they have a messy addressing problem, possible renumbering and flag days on the exchange.
