CTypes and CFFI still work with PyPy. Also, 'not all of it'- well yes, this is a WIP with a ~2 man project/implementation. Not bad. What are you using that's not on the list? The intention isn't so that authors have to test against PyPy.. PyPy's intention is to be as compatible with CPython as possible.

Either way, while you attempt to discredit PyPy the fact remains that Python code is and can be very fast for CPU heavy work. There's no way around that other than trying to poke holes.
