There are enough uses of SA_SIZE() by functions which are perhaps called
both from a sysctl handler and for queuing the routing messages into routing
socket queue.  In the later case, we cannot know ABI of the reader.  This
is what I referenced when I noted that routing socket's ABI compat is
impossible to implement correctly.
