The answer is "yes". The Recursor supports forwarding (both recursive
and non-recursive) and RPZ[1]. The only thing missing in this experience
is IXFR creation on the Authoritative Server's part, as that is
architectually not possible as we do not keep track of records removed
from the database.

Moreover, the DNSBL experience can also be approximated by using the Lua
scripting functionality in the Recursor[2] to block queries based on a
loaded list.
