Kind of silly, actually. The upstream peer can just peer with them as AS23456 without any real issues.

Nonetheless, ARIN has plenty of 2-byte ASNs still available and any organization which has a 2-byte
ASN they don't need can return it to ARIN to be restored to the free pool. There is still a significant IANA
2-byte ASN free pool as well.

Why do we specifically need to add these to 8.3 just because some people are having problems with
4-byte ASNs?

I am, indeed, very convinced that they should not be. I am somewhat less convinced that we should not
make some provision for legacy ASNs to be transferred to an organization under an RSA once.

I'm not completely sure the transition to 4-Byte ASNs is actually going any more smoothly than the transition from IPv4 to IPv6 and there may be similar argument to allow the transfer to 2-Byte ASNs as for IPv4.
