You probably want to look at the other link in that PR, which demonstrated how well copy-and-patch can do for another dynamic language (Lua): [1]

Of course, whether or not CPython could eventually make it to that point (or even further) is a different story: they are under a way tighter constraint than just developing something for academia. But copy-and-patch can do a lot even for dynamic languages :)
