SEND implies the use of a PKI. That's non-trivial. Besides, the expectations for IPv6 are similar to those for IPv4. Somehow folks have been able to secure the ipv4 first-hop (when/where needed) without the need of understanding something like SEND, or going through the hassle of deploying it. So the question "Why do I need this for IPv6 when I never required it for IPv4?" may not an easy one to respond.

I don't seem to remember any major OS that ships with SEND enabled by default -- e.g., that configures CGAs over traditional SLAAC or RFC7217. Additionally (and ironically), the use of IPv6 EHs tends to be rather unfriendly to first-hop security.
