I've only filed a couple of radars, but actually received pretty good response. However, they weren't api-related.
One was about an issue I was having running the Britannica encyclopedia. I don't recall what it was, but Apple even called me about it.
One was about a bug in Lion, where if you pick a large desktop image, and tile it, it gets all corrupted and there are artifacts in the desktop image that respond to movement of windows above the desktop. The corruption of the image looks like what happens when CIAffineClamp is applied to an image: a row of pixels at some place in the image is repeated out to the edge of the screen.
The response was that it was fixed in a point release, but the fix was to disable the Tile option for large images. Except if you have it set to alternate images periodically, with the Tile option selected, a large image can still be tiled and displayed incorrectly.
