> This while we have elephants in the room such as packaging. Researching best practices to move away from setup.py right now takes you down a rabbit hole of (excellent) blog posts, and yet you still need a setup.py shim to use editable installs, because the new model simply doesn't yet support this fundamental feature.

You can do editable installs with poetry, I do it every day.

Just run this: \rm -rv dist/; poetry build --format sdist && tar --wildcards -xvf dist/.tar.gz -O '/setup.py' > setup.py && pip3 install --prefix="${HOME}/.local/" --editable .
