Hi Chris Gillum (@cgillum) , please review and approve when you have a moment.
The latest PR introduces several breaking changes, which I’ll leave to the repository maintainers. This update is minor and does not impact the current implementation.

LGTM! Thanks for this PR! I assume that there will be some follow-up work, similar to PR #131, which will complete the feature?
