For most 2D/3D games using ECS, which is something somewhat popular right now, you can definitely easily abstract the editor, in the manner flohofwoe mentioned for example. Same for other systems. A few minutes using Unity3D are able to demonstrate that: Unity's interface is quite transparent about the abstractions it uses. Also, Unity3D itself uses the extensibility of its own editor to add advanced editing features, so it's already something industry-proven.
