I did not like, difficult troubleshooting in case something goes wrong (however I can understand it's a nice feature to have and in might be useful in some scenarios).
Your experiment predates extended nexthop encoding, but otherwise it is indeed the very same thing. Just less operational overhead now. Of course everyone has done 6PE and 6VPE longest time, because obviously you can fit IPv4 next-hop in IPv6 coding, so nothing was needed. This extended nexthop encoding only exists to fix the problem that wire-format didn't support signalling IPv6 next-hop for IPv4 NLRI. -- ++ytti
