In this case it's not a bug because the ceiling of the sector is not drawn; it's replaced by the sky. The sky flat itself is irrelevant, as long as it's the sky flat it's replaced by the sky, so the ceiling's offsets and angle do not matter, they modify something that is not visible. I agree that being able to control sky rotation on a sector basis can be useful, and that using ceiling angle for that (or floor angle, for a sky floor) would be logical, but that's definitely a new feature -- call it improvement or enhancement if you want.
It may even need to get a MAPINFO keyword to enable, if there are maps that would apply unwanted angles to skies as a consequence of this change if it were implemented. (Relatively unlikely, but who knows?)
