request-nsid seems to not be working (Bind 9.11.3)

from the Bv9ARM: (9.11.3)

If yes, then an empty EDNS(0) NSID (Name Server Identifier) option is sent
with all
queries to authoritative name servers during iterative resolution. If the
server returns an NSID option in its response, then its contents are logged
in the resolver
category at level info. The default is no.

Seems to suggest that they get logged at the info level.
