Describe the feature you'd like to have.
When describing how data should be replicated, we have 3 methods defined: Snapshot, Clone, and None. The "none" method was originally meant to signify that neither a clone nor a snapshot would be used, so there would be no point-in-time image.

I propose to change None to Direct. That is to say, we are copying data directly to/from the PVC.
