Please don't. Python 3 was so painful because we decided to make
millions of tiny backward incompatible changes. To have a smooth
Python 4.0 release, we should only remove things which were already
deprecated since at least 2 cycles, and well documented as deprecated.

Note: The Gtk project has similar questions on backward compatibility ;-)

(Migration to Gtk3 was also painful for developers, no?)
