When using a scene in nodejs using the scoped modules why do I now have to do:
import '@babylonjs/core/Physics/physicsEngineComponent';
Because if I don’t then node tree shakes it and I don’t have access to scene.enablePhysics, I swear it was working two days and I didn’t need that import statement and then without updating anything it just broke, is this a bug, why would the scene file not already import that, or am I just going crazy and thats the way it always was?
We change nothing on that front 
You need to import it if you want to run physics simulation. If you do not need physics then you can remove that import
