I’ll mark this as a feature request. It’s worth noting that if a property name starts with an underscore (like with _expandedData and _flattenedData), it means that it’s internal and it can change or be removed without any sort of deprecation period.

Thank you for submitting your feature request! Looks like during the polling process it didn’t collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular’s scope, we’d encourage you to collaborate with the community on publishing it as an open source package.

You can find more details about the feature request process in our documentation.
