Because you generally don't want to give the configuration file writer
full control over the Python virtual machine.

Which only works if there is only one configuration file per
installation of your package, and is writable by the users that need
to configure it. For example, per-user database connection parameters
should be in $HOME/.programrc on UNIX systems. A program's preference
settings should be stored in a user-writable file to, preferably in
the user's homedir.
