A patch for python script node for the compositor

I’ve found a patch here that adds several customizable nodes to the compositor. I see the python script node very interesting. I can make my own custom compositor effects with few lines of code without need to rebuild blender with new nodes. I wonder if this patch can still be applied to the official blender version for use in the latest version. How can I suggest this patch to the official blender? thank you.

It looks like the patch is about 3 years old. I would be surprised if it can be applied to master without a lot of work.
