This is the solution Cumulus is advocating to its users, so I suppose they have some real users behind that. Juniper also supports RFC 5549 but, from the documentation, the forwarding part is done using lightweight tunnels.
I'm not sure if you claim otherwise, but no real 'tunneling' takes place, as far as I know, it's internal implementation detail having IPV6 next-hop for IPV4. I don't think there is any additional headers or any additional lookup or cost. Cisco supports extended nexthop encoding too, so it is fairly well supported by shipping products. -- ++ytti
