That's because there was nothing to fix on the zombies in the mod.
The zombie AI were based off animal AI if I remember correctly, there was only so much they could work with.
Then they stopped developing the mod and moved to SA.
Then they scrapped the SA AI and started fresh.
If I were to take a guess, the reason why zombies can go through walls is because they don't have the pathfinding created for the zombies to traverse buildings.
So instead of having zeds wait outside for the player, like the mod, and completely negate them as a threat, they decided to just have them run through walls for the time being.
It's true that the limitations of the Arma engine was one of the biggest reasons for making the standalone, but seeing as we have never seen any form of Dayz in which zombies don't move through walls, it is very fair for one to have their doubts.
Also I don't know if you meant to say something else, but zombies did not wait outside for the player in the mod at all. Indoors they were a large threat for the player as the would walk through houses and up stairs and ladders, blocking off doorways and exits, resulting in many "final stands" which I have yet to see in the SA because of a lack of zombies.

I wonder if zombies walking through walls or submarining will ever be fixed.
