Ipv4_addrs var while nice can get very lengthy very quick and then more prone to humanized errors. If you add ipv6 in there it grows horizontally tenfold.

There just isn't an easy way around this unless we were to for say  . . . 
/etc/ifconfig_ipv4
/etc/ifconfig_ipv6

And then read in the lines one by one as . . . 
$INTERFACE $ADDR $OPTS


Personally I like the way Debian handles this but I really only see a need for handling it the initial way I wrote about non-sequentially which puts it fairly close to how they do it.
