Thank you for the proposal. While this is a useful feature for some use cases, it feels too specific to be included in the core library. This behavior can be achieved by using the chart-options attribute in combination with the chartjs-plugin-annotation plugin. We prefer to keep the core library focused on general-purpose charting.
