Ubuntu 20.04 LTS, Python 3.8.3, Django 3.0.8, Poetry setup VENV

Inside a poetry generated virtual environment with only the following
dependencies and their required dependencies:
{{{
[tool.poetry.dependencies]
python = "^3.8"
django = "~3.0"
}}}

I have a poetry initialized project setup, which has generated the
following structure.
{{{
(devenv-demo-Iq-p0dca-py3.8) d@devpad:~/development/devenv_demo$ find .
.
./poetry.lock
./pyproject.toml
./tests
./tests/__init__.py
./tests/test_devenv_demo.py
./devenv_demo
./devenv_demo/__init__.py
./README.rst
}}}

The only overlapping file is inside our devenv_demo directory:
{{{
__init__.py
}}}
Which contains a single line of text:
{{{
__version__ = '0.1.0'
}}}

Upon running the following command we run into CommandError:
{{{
(devenv-demo-Iq-p0dca-py3.8) d@devpad:~/development/devenv_demo$ django-
admin startproject devenv_demo .
CommandError: /home/d/development/devenv_demo/devenv_demo/__init__.py
already exists. Overlaying a project into an existing directory won't
replace conflicting files.
}}}

This still causes some of the template files to be created by
startproject:
{{{
(devenv-demo-Iq-p0dca-py3.8) d@devpad:~/development/devenv_demo$ find .
.
./manage.py
./poetry.lock
./pyproject.toml
./tests
./tests/__init__.py
./tests/test_devenv_demo.py
./devenv_demo
./devenv_demo/urls.py
./devenv_demo/wsgi.py
./devenv_demo/__init__.py
./README.rst
}}}

However as it encounters an already the existing __init__.py it fails and
stops creating more files since we are still missing:
{{{
./devenv_demo/settings.py
./devenv_demo/asgi.py
}}}

According to: https://docs.djangoproject.com/en/3.0/intro/tutorial01/

Removing the conflicting file ensures complete normal functionality of
'django-admin startproject'.

Comment:

As far as I'm aware, a fast failure is an expected behavior in this case.
We treat already existing files as a error, so there is no point in
creating remaining files.
