How to detect World changes without using generics

Hello.
I'm implementing Unity's [EntityViewer](https://github.com/kurobon-jp/DefaultEcs.Unity.EntityVisualize), but since I can't find a way to detect World changes without using generics, I’ve had to resort to a rather [heavy-handed approach](https://github.com/kurobon-jp/DefaultEcs.Unity.EntityVisualize/blob/main/Assets/Editor/DLLModifier.cs). 
Is there a better way to handle this?
