Hi Arvin,

Thanks for the KIP.

Unfortunately, I don't think this makes sense since it would increase the amount of data we send back in the metadata response, which is pretty bad for scalability.  In general we probably want to avoid the case where we don't have the appropriate number of in-sync replicas, not try to optimize for it.

best,
Colin
