Unity Roadmap: Optimization

I have seen that Unity has GPU / CPU optimization on their roadmap.
I would really like to find about what exactely they will be improving and contribute to it by giving them my projects.
I am not sure how they can improve GPU / CPU performance without knowing about user scenarios.

could be that some of those below are coming up and more (if not already in latest versions)
