How deep can TD go into the core of IL2? Just read this post? Is it possible?

I was under the impression that they could alter the core of the program. They did so when the created the new dt.dll file in 4.10 which improved the AI by a leap and a bound. I think they could do something even deeper if they had the desire to. Doubt they have the time and inclination to do it except for the really big must haves.
