With "the cloud" allowing for effective single homing these days, do we really need to codify any sort of multi-homing requirement? I also don't see the utility of a list of reasons that someone can be assigned an ASN. Isn't "I'm connecting to a network and speaking bgp" good enough.
16b are scarce and special, and one application where you really want to have 16b ASN is when you have >1 upstream and >0 downstream, then you really want to support TE via communities, and for this you are in competitive disadvantage without 16b ASN.
The need for TE communities may already exist with multihoming to a single upstream AS. E.g. TE comms to modify localpref to make a link strict-backup in multihoming-to-single-upstream situations.
