Currently we use the BIND code base in two packages:
- dnsutils from [core] provides basic DNS query tools;
- bind from [extra] is the actual name server.
We already have ldns in [core], a much better written (and sane) DNS
library which includes query tools that are near drop-in replacements
for BIND's: use `drill` instead of `dig`, etc.
One observation - bind is the de facto standard and as far as I
can tell used by the majority of the root servers  (and the majority
of all major DNS servers according to wikipedia  and bind website 
We may want to be cautious stepping away from the dominant DNS
software unless there is a sea change for the DNS community to do same.
A casual look around  - so clearly I am not in the know here
- but the rewrite seems not dissimilar to the postfix "re-write" of
sendmail - modularity and security seemingly key goals. 
Anyway, I'd encourage that we try and stick with bind.
 I am not familliar with ldns or it's benefits - security or other so
I don't feel entitled to an opinion.
