All providers maintained by the Crossplane community mirror Crossplane's support
of the `--debug` flag. The easiest way to set flags on a provider is to create a
`ControllerConfig` and reference it from the `Provider`:
`DeploymentRuntimeConfig` and reference it from the `Provider`:

```yaml
apiVersion: pkg.crossplane.io/v1alpha1
kind: ControllerConfig

Providers can also be paused when troubleshooting an issue or orchestrating a
complex migration of resources. Creating and referencing a `ControllerConfig` is
the easiest way to scale down a provider, and the `ControllerConfig` can be

modified or the reference can be removed to scale it back up:
