Last year, we updated pyproject.toml, see this diff. We should update it this year too. In a future PR, I think that you should include yourself as a schema author in that file, considering that you were the main developer over several years.

Good catch. I didn't notice Nicholas changes the file path and thought it was removed (but it's in the root directory now).
I think the authors here are contributors to the poetry setting, so I won't add my name.

Thanks Jie! Nevermind about the Poetry file then, my bad.
