 Here are the reasons:

 - 127.0.0.1/8 will be configured on lo0 in rc.d scripts if
   ifconfig_lo0 is missing after processing ifconfig_IF and before
   doing ifconfig_IF_alias*.

 - You cannot manually configure ::1/128 because it is configured by
   the kernel when a loopback interface becomes "up".  If you have an
   ifconfig_lo1 and no ifconfig_lo0, ifconfig_lo1 will be processed
   and make lo1 "up" first.
