The launcher implements shebang support for directly running Python
scripts in multiple versions and virtual environments, including
virtual commands (defined in py.ini) to support other implementations
such as PyPy. It can also be used to administer multiple CPython
installations from the command line.

If you don't need it, don't install it. You can install it later if
you change your mind.
