The changes aren't complicated. You only need to understand special "<<>>" marker.
The syntax of ranges of versions in packages not supporting installation for multiple Python ABIs
won't be changed. Majority of ebuilds won't need to explicitly use any extended functionality
of PYTHON_DEPEND. In ebuilds, which support installation for multiple Python ABIs, unconditionally
depend on Python and don't need additional USE dependencies on Python, I will unset PYTHON_DEPEND,
because it will work like PYTHON_DEPEND="<<>>".
