My experience is that some people avoid setting up new projects as much as possible. Some people love creating new projects and customize and automate the hell out of it. Most everyone else is just trying to minimize the pain of new project setup. Having to download and evaluate tools for automating project setup is pain. I think this middle group just goes with the first thing they run across that could possibly work. Maybe they hear about it from a coworker or a blog post or a google search, they just want to get it over with and move onto something they feel is less painful.
I agree there is no consensus. There is popularity though. It is almost a king of the hill situation where the most popular project setup option is constantly getting knocked off the throne.
Even though I enjoy project creation, I try to minimize the time I spend thinking about it. In my opinion, the winds of change blow too quickly.
