I see this only made its way to 3.12 kernel, what is holding up inclusion
in other kernels? (or maybe this question should be directed at someone
else?)

The bug was introduced with:
commit c319b4d76b9e583a5d88d6bf190e079c4e43213d
Author: Vasiliy Kulikov <segoon@...nwall.com>
Date:   Fri May 13 10:01:00 2011 +0000
    net: ipv4: add IPPROTO_ICMP socket kind

starting with 3.0.
