Open source versions of BIND, including 9.11.5-P4, do not support
recursive use of the ECS option.

There is a branch available to ISC support customers that does
(contact via https://www.isc.org/support for more information).

The feature may be included in an open source branch in the future, but so
far we've hesitated out of skepticism that ECS is a good idea that will be
needed very much in the long term - we don't want to have to support it
forever if it fizzles. But we do revisit the conversation periodically.
