Thanks Vyas! 🙏

Had a few comments about changes in the pyproject.toml and whether we can address these in dependencies.yaml

[vyasr]

Thanks for the comments John. This PR isn't quite ready for prime-time yet, but you did catch a couple of important issues for us to address before it's ready 🙂

[jakirkham]

Ah sorry. Was mainly excited to see the increased usage of pyproject.toml 🙂

Happy to hold off further review until things are more ready 👍

[vyasr]

@jakirkham this is ready for review now 🙂

I'm unsure what benefit we are getting from the new sections in dependencies.yaml. See comments.
