So, the project you linked has a pyproject.toml file uses flit:

    requires = ["flit_core >=3.2,<4"]
    build-backend = "flit_core.buildapi"

Python.org defaults to using hatchling in the docs[1].

PyPA has a sample repository using setuptools[2]. This project is linked from Python.org on this page.[3]

Python.org recommends using setuptools under packaging recommendations as well, with no mention of hatchling or flit even on that page.[4]

No wonder so many devs are frustrated about this. I've been writing mostly Python for work and fun the past 11 years and I'm f*cking confused what tools to use. When I start a new side project I don't know whether a tool is going to exist and still work in a few years, because there's 10 tools trying to do the same things and it's not clear what the community is actually getting behind.
