I think it will be very rare to find a program that works on both but
only on different MAJOR.MINOR versions. It is *possible* - for
example, we have an ast.py in Jython 2.5 even though CPython does not
get this until 2.6 (ast.py as a replacement for pyc bytecode
manipulation was just too compelling for us to ignore).
