It simplifies the process of managing and installing apt packages required for a development environment by specifying them in one file.

Additional Information:

Based on the approach found in https://github.com/heroku/heroku-buildpack-apt and https://docs.digitalocean.com/products/app-platform/reference/buildpacks/aptfile/.
