Do you think that pushing the KitKat launcher to everyone would be a good or bad idea?

So Basically on Android Police a while back a post was made saying that the KitKat launcher might be pushed to every android device in the form of google search updates. Although the Google Search apk is also the launcher on the nexus 5 it's is probably just to improve the slide to the left for google now feature. So it probably won't happen, but if it did what do YOU think the outcome would be? Here are a few questions.
