Why isn't that an answer?

If we make it optional and some wikis don't switch, those wikis will be still face the same issues for new users as before. I know veterans often don't feel, as they are already familiar with how User Talk page work, but I don't think anyone will argue that User Talk pages are easy and intuitive. Even for those that know how to use them they take more time to answer someone than Message Wall does.

It could be argued that it will be even worse because those users could get confused. On less serious note: If someone from Wall-enabled Wiki comes to Wiki without Wall it would be even harder for them to adjust to the medieval ways of User Talk pages, when they already are comfy with their cool Message Wall :)

Another answer that I've already given: Making Wall optional or not is not up to me. I can only work on making it better and on addressing whatever issues You might have with it.
