What's the latest status on this? It's still marked as a draft so I assume there's more to do?

[slayyden]

This is feature complete and awaiting review for code quality and robustness.

[Keavon]

Any updates about getting the two code review comments resolved? (The question and the suggestion to reuse the existing winding function instead of reimplementing it.) Thanks! (I'm also going to mark this as a draft for the moment until I hear more.)
