Changes to the `Shoot` worker-pools are applied in-place where possible. In case this is not possible a rolling update of the workers will be performed to apply the new configuration, as outlined in [the Gardener documentation](https://github.com/gardener/gardener/blob/master/docs/usage/shoot-operations/shoot_updates.md#in-place-vs-rolling-updates). The exact fields that trigger this behaviour depend on whether the feature gate `NewWorkerPoolHash` is enabled. If it is not enabled, the fields mentioned in the [Gardener doc](https://github.com/gardener/gardener/blob/master/docs/usage/shoot-operations/shoot_updates.md#rolling-update-triggers) are used, with a few additions:

- `.spec.provider.workers[].dataVolumes[].size` and `.spec.provider.workers[].dataVolumes[].type` (only the affected worker pool)
- `.spec.provider.infrastructureConfig.identity`

Strictly speaking not complete. There are still some calculated values I need to understand (again) in order to add a mention to them.

I will give the suggestion to have a line per sentence. While the produced output still concatenates these into a single paragraph, it is easier to review with the line per sentence.
