Django: Using the <startapp> Command

Why does using python3 manage.py startapp vetoffice not modify the INSTALLED_APPS list within the project’s settings.py file? If it can automatically create a folder (for the new app within the project), then why is it somehow unable to also update the INSTALLED_APPS list too?

Seems weird to me that Django is like: “Oh, let me automate all of this for you; EXCEPT you’ll have to manually update the INSTALLED_APPS list yourself.”
