AI modding has been possible so far using descr_formations.txt and descr_formations_ai.txt.

Is it possible to make a text file that governs when archers stop marching to start firing, or something that influences flanking? It sounds complicated, but i wonder if its at all possible for non-programmers...

Perhaps in the future...
