Yes, I agree completely.

I believe it's a performance hack.   The lo0 interface has an MTU of
32768, instead of 1500, and probably does less work on each packet.

Netstart doesn't need to parse the ifconfig.xx files - they are
completely opaque to it.   All it does is make sure that ifconfig is
called once for each line in each ifconfig.xx file.
