Pathfinder doesn't do anything special in that case; it has the same limitations as stb_truetype. There's probably a way to fix these issues if they come up in practice. I would recommend doing the trapezoidal area approach in spite of these limitations. Having 256 shades of gray instead of 8 or so makes a big difference for all paths, not just pathological ones. It often ends up faster than MSAA, too.
