Our team has worked on a feature for Unity 2020.1 to provide better context when editing Prefab assets. You can try it in the beta now - let us know how it's working out for you!
We've made some improvements to the Prefab workflow: you can now see the context of the Prefab instance in the Scene view while editing the Prefab asset!
