It was intentional, yes, and described in the patch description (for
both the kernel and refpolicy) and in the inline documentation for the
policy capability in refpolicy. I chose to address all known gaps in
our ability to distinguish among sockets at once.
Note btw that icmp_socket is only used for the unprivileged ICMP
sockets (aka "ping sockets") created via socket(PF_INET, SOCK_DGRAM,
IPPROTO_ICMP) or socket(PF_INET6, SOCK_DGRAM, IPPROTO_ICMP6).
rawip_socket is still used for SOCK_RAW ICMP sockets.
