Redis [QUESTION] Why CLUSTER RESET doesn't forget all nodes first?

The CLUSTER RESET command for a replica flushes dataset first, and then forgets all nodes. There's a problem when I reset a replica with a large dataset， it may take more than 1 minute to flush the dataset. That causes the replica will be re-added into the cluster again. So why CLUSTER RESET doesn't forget all nodes first ? If that, will it be able to avoid to be re-added into the cluster again during the process of reset?

Maybe it's better to forget before flush. I don't know if there would be any drawbacks. @madolson WDYT?
