Can the reporting task job also be seen as a role?

So, instead of

spec:
  clusterConfig:
    createReportingTaskJob:
      enabled: true
      podOverrides:
        ...
  nodes:
    roleGroups:
      default:
        podOverrides:
          ...

would it be better to create a top-level struct

spec:
  nodes:
    roleGroups:
      default:
        podOverrides:
          ...
  reportingTaskJob:
    enabled: true
    podOverrides:
      ...

?

Update: Proposal withdrawn after a discussion.

Sure, we could also use spec.reportingTaskJob instead of spec.clusterConfig.reportingTaskJob.
However, this would be the first case we do that AFAIK, so far we always stuffed config that can only be configured on the whole stacklet below clusterConfig.
