Wrapper components

WrapperComponent.fusion

prototype(Vendor.Site:Example) < prototype(Neos.Fusion:Component) {
  foo = null
  bar = null

  renderer = Neos.Fusion:Component {
    # pass all outer props to the renderer
    @apply.props = ${props}

    # alternatively pass explicit props to the renderer  
    foo = ${props.foo}

    # calculate additional props based on outer props
    barTransformed = Neos.Fusion:Map {
      items = ${props.bar}
      itemRenderer = ...
    }
    
    renderer = afx`...`
  }
}

Totally agree @private is nowadays the way to go
