Current answers are quite obvious and intuitive:

- All names resolved via resolver are resolved using the DNS 
  servers specified.  Nothing more.

- If one want to specify static mapping, he/she can use upstream{} 
  blocks to do so.

Trying to introduce additional sources of information will 
inevitable add more questions with not-so-obvious answers.  Not to 
mention that the next step will be to add nsswitch.conf and other 
sources it supports, as well as source ordering.  And this is 
certainly not something we want to add.

So I think the main question here is: why it should be added, if 
at all?  Which problems this feature is expected to resolve?  
Current answers does not seem to outweight questions added / 
support costs of this feature.  Especially given the fact that 
code suggested is far from being committable.
