Of having AS numbers in the IP packet isn't actually all that bad. It's just a matter of where. This comment (https://news.ycombinator.com/item?id=23418691 https://news.ycombinator.com/item?id=23418691) from elsewhere on the thread suggests making the ASN the top 32 bits of the IPv6 address, which would solve a whole slew of issues.
Clients don't (and shouldn't) care about the routing information built into the address, but building the ASN into the IP address isn't so bad. And to keep things compact, the ASN could be in little endian order.
