It changes the KBI, though.  I maintain a third-party kernel module
that uses sockets (it will hopefully hit the Ports Collection this
week); since this addition is at the end of the struct, it is probable
that this module will not need to be recompiled, but I haven't yet
checked.
That said, I hear __FreeBSD_version bumps are cheap.
