Module Question: How to write a module that replaces a core piece of the engine?

[moonshineTheleocat]

I am currently working on a project, and due to the nature of the project, and the target I need to write a few modules to replace some core components of the engine.

Specifically the Renderer, and the Physics system.

The documentation states that you can use a module to replace the current renderer, and the physics system. But it is only a hint. There's no information about how to do this correctly.

Can someone point me in the right direction?

As far as I know, modules can't provide renderers or physics engines yet. I remember hearing this is planned for 4.0, but I can't confirm it.

Well, modules/bullet is a module that registers a new physics engine :)
But indeed there's no similar feature for renderers AFAIK.

Implementing custom renderer would certainly become relevant with the drop of GLES3 backend in 4.0, which godotengine/godot-proposals#877 proposes to retain.
