Without this, one has to call chmod() after bind(), leaving a window where threads can connect to the socket with the default mode. After bind(), fchmod() reverts to failing with EINVAL. This interface is copied from Linux. The behaviour of fstat() is unmodified, i.e., it continues to return the mode as set by soo_stat().
