sweep() should accept closed sketches

[yeroca]

I feel like sweep() ought to be able to take a closed path (profile). Otherwise, I need to make the object from two sweeps instead of one. Am I being unreasonable in this?
Here's my example:

sketch001 = startSketchOn(XZ)
profile001 = startProfile(sketch001, at = [0, 5.02])
|> yLine(length = -4.13)
|> tangentialArc(endAbsolute = [0.98, 0])
|> xLine(length = 2.04)
|> tangentialArc(end = [0.99, 1.15])
|> yLine(length = 4.01)
|> line(endAbsolute = [profileStartX(%), profileStartY(%)])
|> close()

sketch002 = startSketchOn(XY)
profile002 = startProfile(sketch002, at = [0, 0.11])
|> yLine(length = 24)
|> tangentialArc(end = [-5, 5])
|> xLine(length = -24)
|> tangentialArc(end = [-5, -5])
|> yLine(length = -24)
|> tangentialArc(end = [5, -5])
|> xLine(length = 24)
//|> tangentialArc(endAbsolute = [profileStartX(%), profileStartY(%)])
// |> close()

sweep([profile001], path = profile002)

but if I uncomment the tangentialArc and close, I get an error saying the Requested trajectory curve is invalid.
