Vaporware part is true, upto now, operational value is to be seen.

Did you notice that 32bit ASN's are coming and that IPv4 addresses are
32bits? :) Which effectively means that we are going to route IPv6 with
an IPv4 address space. Or when one would use the 32bit ASN for IPv4:
routing a 32bit address space with an 32bit routing ID. The mere
