tl;dr I proposed a solution for Python's weak multi-core story (note I didn't say "support"), but didn't have time to follow through. I still have hope, both for the project as a whole and for several standalone parts.
[Update 8/2018] I picked this back up after a break and am aiming for Python 3.8. See this project and PEP 554. <fingers_crossed/>
