You can complain all you want about the spit being over modeled from what I've seen of pilot interviews it was a very well handling plane. So why should HT make it worse just because it was a great handling plane in real life?
The spit also has it's weakness it's a easy target to shoot down if you get your guns on it.. It doesn't stand a chance in collisions meanwhile many other planes can easily land after a collision that would have taken down a spit. If someone pings you it doesn't hold up so well either, the wings fall of a spit as faster than any other plane I've seen.
Another thing I can say about most of the spits, is the guns are somewhat weak. So for every advantage it has disadvantages. As a side note I've been flying the spit 9 most of the time lately and while it may be a good plane, there are many that can out do it in many diffrent ways.
