Yes, there is no code to handle them, because it needs a lot of work to write it.
But it will be a valuable enhancement.
Remember these polygons (as any polygon used in Kicad) must be never self intersecting to avoid
breaking Gerber files (and better: must be strictly simple polygons after edition).

So this is like DRAWSEGMENTs of S_POLYGON but not filled, and can be self intersecting.
