IMHO trying to have a binary compatibility with older compiled modules
by maintaining an ad-hoc layer to switch between 2.4/2.5 engines make
Python code more complex. And more complex code have generally more
bugs. This is the reason for my KISS hope about Python.

Its simple to require changes, not so sure that doing these
modifications keep things simple. Maybe an internal Python hacker can
give us his advice on such a modification (ie. staying compatible with
legacy modules compiled for previous versions).

A+
