Not a problem per se, but it would be great to use a better package manager and pin deps using something better than pip-compile. Handle the "extra_requires" properly

Describe the solution you'd like
Set up poetry, adapt the documentation and CI scripts to reflect that

Describe alternatives you've considered
Writing our own, pip-tools/pip-compile
