Care to elaborate on why ReadFrom.ANY isn't sufficient?

[omer-cilingir]

Sorry for not explanation,
All the write commands go to the master node, the master is already busy and has high CPU usage, so the get commands go to only the replicas, so we can distribute the load & CPU usage.
This setting may be useful for applications whose the write is half the read.

Thanks a lot. From that perspective, it makes sense to add another constant.

Thank you for your contribution. That's merged, polished, and backported now.
