Why should it? Distributions are going to make their own decisions independent of the PEP. That's why s/would/might/ in the above change. I'm open to suggestions for better ways to explain it. I meant how these decisions are implemented. Is there a configure switch (there doesn't seem to be)? Does it require patching Python?

Ah, no. Standard configure switches are used. Debian (inherited by Ubuntu) has a post-installation script for Python packages which create the .py symlinks and do the byte-compilation. The big win here is that much of this can go away now (and in fact there are modifications to this post-installation script already).
