It's to keep compatibility for Python 2 only scripts.
It doesn't mean Python 2 is default Python.
Debian and Ubuntu working hard to move Python 3 as default.
Most packages depends on Python 3, not 2.
When installing Ubuntu, there are no "python" command.
Python 3 is installed as default, but Python 2 not.
