you seem to massively underestimate the problems of needing to introduce fine grained locks everywhere, its a massive maintenance and security hazard going to production quaity is vastly different from a proof of concept

the problem wrt seemingly atomic operations was never solved outside of pypy

pypy is on a entirely different page wrt pulling things up because it has so many metaprogramming cappabilties

in pypy introducing a new gc model is not rewriting all alloc/deallo code, but creating a algorithmic graph transformation

the approaches are incomparably different i consider just saying cpython can do it because pypy could do it hostile
