`--experimental-patches` is now deprecated and will be removed in a future release. You can migrate to using the new flag `--patches`.

For the time being, these flags can be mixed with `--config`, but that might change in the future. On a command line, the last *patches flag takes precedence...

Pruning requires that CRD developer provides complete, structural validation schemas, either at the top-level or for all versions of the CRD.
