It worked with any policy source not just Farsight. However, is no longer 
necessary since isc now has a native RPZ implementation. Thanks for that.

Hello,

In line with ISC's deprecation policy, I am notifying the mailing list
of our intent to remove support for Response-Policy Server support.

Back in 2018, Farsight Security[1] contributed a patch to BIND that was
an optional replacement to our native RPZ implementation. At that time,
our RPZ implementation wasn’t scaling very well, and we accepted
the patch. This patch, however, only worked with Farsight’s own RPZ
service, so its utility is limited to Farsight customers. We do not think
this patch really belongs in open source BIND 9 version. Removing the
feature that has limited user-base will allow us to improve the RPZ
(Response-Policy Zones) feature that's native to BIND 9 and available
to all BIND 9 users.

The feature is called DNSRPS, or the Response Policy Server. Farsight
called it “FastRPZ”, but in the ARM it is called the Response Policy Server[2].

The support for DNSRPS/FastRPZ will be deprecated as of BIND 9.20
and removed in BIND 9.21/9.22.

1. Since then Farsight Security has been acquired by DomainTools.
