It should probably check if

kern.features.inet6: 1
kern.features.inet: 1

are set and only add v6 and v4 in these cases;  you could go further and 
check how ipv6_prefer is set in case both are there and make the order 
dependent on that ..

All will be just more magic to automystriously break things some way ..  
The reason I don’t like these kind of scripts a lot is that we have a 
handful of places all thinking they should manage resolv.conf manually 
in their own way rather than using one thing.
