add ability to not answer (not even SERVFAIL)
It seems that testbound has some support for this in TIMEOUT, see https://github.com/NLnetLabs/unbound/blob/release-1.6.4%404248/testcode/replay.c#L302 .
Example of test using this is: https://github.com/NLnetLabs/unbound/blob/release-1.6.4%404248/testdata/fwd_timeout.rpl
Investigation is needed as first step:
-
How does it behave in testbound? -
Does it make sense to implement it in Deckard? -
If not, how can we simulate timeouts?
