Since Kafka require all the reading happens in the leader for the consistency.

If there could be possible for the reading can happens in replication, thus, for data have a number of consumers, for the consumers Not latency-sensitive But Data-Loss sensitive can fetch its data from replication, in this case, it will pollute the Pagecache for other consumers which are latency-sensitive
