BIND 9.21.20: DNS Error Reporting Logging and Resolver IP Addresses

I've recently been experimenting with the DNS error reporting features in
BIND 9.21.20. I've noticed that when a monitoring agent logs a received
error report, the log entry doesn't include the IP address of the resolver
that sent the report. Is this by design? If so, is it something that might
be added in the future? My logging config looks like this:
logging {
channel error_reporting {
file "/var/log/named/agent.log" versions 30 size 25k;
severity info;
print-time iso8601-utc;
};
channel query_log {
file "/var/log/named/query.log" versions 30 size 25k;
severity info;
print-time iso8601-utc;
print-category yes;
print-severity yes;
};
category default { default_syslog; default_debug; };
category dns-reporting-agent { error_reporting; };
category queries { query_log; };
category unmatched { null; };
};
Thanks for any insights,
Scott
