I've also used them because I
  - need other record types (e.g. SRV)
  - want to use DNSSEC
  - Want to choose between recursive and stub resolvers

FWIW, I use http://25thandclement.com/~william/projects/dns.c.html in many
projects.
It parses nsswitch.conf, but only cares about a few predetermined values.
Maybe it should gain some features in this area?
