Question: Consumer group topic metadata

[p53]

Hi,

when doing

/usr/local/bin/kafkacat -b localhost:3000,localhost:3001,localhost:3002 -C -G mygroup funny_f72d5845-177a-46fa-ad53-008a12a8d923

i see that kafkacat is doing metadata request with empty topics in metadata request, means requesting all metadata, i cannot find code where it is doing, but it would be better if it would only request metadata of those topics?? If there would be flag for it or some automatic process, it would be great

What librdkafka version are you using? (kafkacat -V)
