Relax pyproject.toml requirements?

Would it be possible to switch the == to >= in pyproject.toml?

I'm considering packaging python-libzim for nixpkgs, because pyglossary depends on it for zim input. The only thing is the dependencies in pyproject.toml necessitating an exact version (==) has made trying to package it not really work. I have issues with trying to do the current version because it requires package versions that are newer than in nixpkgs.

I switched to trying to package a previous point release version (3.11.0), so that I can test the package I'm writing for build errors but I get version errors:

 > ERROR Unmet dependencies (checked against /nix/store/d64q19q1xjdwfhqx6czvrjgrhq0n3lcc-python3-3.14.7/bin/python3.14):
>        cython==3.2.4
>           wanted: ==3.2.4
>                 found: 3.2.5
>    setuptools==82.0.1
>              wanted: ==82.0.1
>                found: 83.0.0

I knew that python-libzim was probably packaged in either arch or the aur and looked at the package build and the packager there just uses sed to replace == with >= in their PKGBUILD. (here)

Start in pyproject.toml by reviewing the dependency entries that use exact == constraints, then compare them with the packaging concern described for Nixpkgs and the Arch PKGBUILD linked in the issue. Done means the dependency declarations support compatible newer versions without breaking the package's stated requirements; verify the package can be built with the versions available in the reported environment.
