   > Thanks for the PR. I am tempted to specify list offsets methods to support 0.11.0 brokers and newer. 0.10.x is extremely old now. It was different when we implemented #3098 4+ years ago.
   
   Well, from my POV I'd say that `listOffsets` looks like a feature supported in 0.10.x, it's just the metadata headers sent from `AdminClient` that prevent it from working (if I'm not wrong).
   
   I understand that 0.10.x is an old version, but it's the one that our company uses in Production 🤷🏽 I don't know how many companies are out there like mine, but I'd bet they will be happy to know that if they want to use `listOffsets` for whatever new thing they develop, they are not forced to upgrade the Kafka Cluster version. We all know that nowadays Kafka is a key component in most companies architecture, and performing a major upgrade is a big thing that needs a huge amount of work and synchronization between teams (at least compared with a client update).
   
   That being said, whatever decision you make, will be fine (at least I've tried 🙂 ).
