May want to scrub that out of the proposal then.

Sounds fine.
I'll fill in more details beginning next week, along with some references

I am more interested in the getting the code example in the docs then
making sure the proposal is perfect.

Nope you got it :)

Control points for an arc or circle are always "three": start point, end
point and any point on the middle. Circle just has the start and end at the
same location. If you call the method control points from the start we can
grow the solution for other curves as funding is made available.

No you are fine.
