The previous wording of this entry suggests that CPython won't work if optional compiler features are enabled. That's not the case. The change is that we require C11 rather than C89. Note that PEP 7 does say "Python 3.11 and newer versions use C11 without optional features." It is correct there: that's not a guide for users who compile Python, but for CPython devs who must avoid the features.
