We need a way of identifying any scope creep by viewing the history of a master feature to see if any new features have been linked to it.
This functionality is available at a feature level as you can see all requirements that are linked to it.
Thank you for the idea. This is possible today using the history panel in roadmaps. Open the features roadmap and select the epics toggle. From here you can see features added/removed from the epics included in the roadmap.
