Nitpick: I'd prefer to refactor the namespace parameter to be a dict, with keys: name, labels and annotations, instead of having 3 separate top level parameters like this.

Me too, but consistency is also good.
In the appuio lab:

grep -rh 'namespaceLabels:' dependencies/**/defaults.yml
    namespaceLabels: {}
      namespaceLabels: {}
      namespaceLabels: {}
      namespaceLabels: ${appcat:namespaceLabels}
      namespaceLabels: ${appcat:namespaceLabels}
      namespaceLabels: ${appcat:namespaceLabels}
    namespaceLabels:
    namespaceLabels: {}
    namespaceLabels: {}
    namespaceLabels: {}
    namespaceLabels: {}
    namespaceLabels:
    namespaceLabels: {}
    namespaceLabels: {}
    namespaceLabels: {}

I saw this in quite a few components.
