Well, I cannot configure the same address/netmask pair more than once
for the same interface, I'm getting "file exists" back from the ip
command. FreeBSD looks up the name/address pair.

Well, Postfix used to look at the addresses and deduce the network class
for that, but there have been many complaints by people that this would
get subnets wrong. A couple of months ago, Postfix has started to look
up the netmasks as well.
