That's a 72MB download, and yet another way to fragment the ecosystem. Not something I'd get just to make a package when a default Python setup has recommended tools and everything I need to make and/or install packages.
No it doesn't. Neither setuptools nor pip are part of the standard library. Yes, they are installed by default in many cases, but they are still "extra tools".
If you've solved 1-99 and download size is an issue, you're in heaven already.
Poetry doesn't fragment the ecosystem. Unlike setuptools it uses pyproject.toml, which can be read by other tools, and is the correct way of storing package configuration.
A package built using Poetry is installable without Poetry in the exact same way as one built using setuptools.
