we are defining optional dependencies that can be installed with pip install -e .[dev].

These optional dependencies are meant for the package developer not for someone installing the package from PyPi.

Recently (Oct 2024) dependency groups where introduced and now most package managers (like pip and uv) can use it.

As someone that installs package via PyPi I would like it that any optional dependencies are useful and usable for me.
