Dean,
You are quoting an RFC from 1996 (19 years ago)? What next, the Old Testament? Thou shalt be multi-homed?
I don't think this RFC ever envisioned the IP runout and that networks hosted by businesses themselves (of any size) would need multi-homing and in the reading of this, you could make an argument that no-one needs an ASN and that all their upstreams could host their portable space for them.
Please understand, that I am not suggesting giving an ASN to anyone who has no intention of ever multi-homing.
I am wanting to policy to reflect that if a network operator wants to design their network for multi-homing, that they should be able to, with no requirement to immediately multi-home. At no point did I say 'never' multi-home, or no intention of multi-homing.... the intention should be there.
I'm asking that the policy reflect an operators choice to decide how they manage their networks should they choose to do it that way.
