CPython isn't a JIT because its goals as a portable reference implementation would be much harder to achieve with a JIT.
To put it another way, there's a reason PyPy trails CPython language features on the scale of literal years. This is not explained by the affordances of the language they're written in! They're just projects with very different requirements which, on some platforms, happen to run a lot of similar-looking code.
