   @lucasbru 
   Thanks for your comment! Totally agreed. 🙇‍♂️ 
   I have one more question. 
   Would introducing a new request version for this behavior require a KIP?
   
   If so, would it make sense to cover both the topology hash and the 
corresponding request version bump in the same KIP? We could also specify the 
canonical encoding and hash algorithm there to ensure consistent results across 
client and JVM versions.
   
   Moving topology fingerprint computation to the clients could also reduce the 
Group Coordinator’s comparison workload. This could be particularly beneficial 
for large Streams groups with complex topologies, especially when many members 
join or rejoin around the same time.
   
   What do you think?
