Premature optimization is the root of all evil. Most C extensions use premature optimization
How do you know it's premature? Some extensions _are_ meant for speed.
Extensions that need to squeeze every bit of speed out of the C API are the exception rather than the rule. Making it easier for extension authors to naturally pick portable options seems reasonable to me. Gating the "fast, but unsafe" APIs behind some sort of "opt in" setting seems like a sensible approach. However I agree, making it *impossible* to get right down to the high-speed calls (with the understanding that you're typing yourself to CPython and need to carefully track internal changes) is not something we should do. Python's built an ecosystem around high-performance C extensions, and we should support that ecosystem. Paul
