Robots.txt has been around for a long time, and all the major search engines will honor it. Not having a full index of the Web is the norm.
That isn't to say that the practice of signing agreements isn't potentially a concern. Not sure that I like the idea of search engines paying sites money to degrade search results of competitors.
What isn’t the norm is to serve one robots.txt to one company, and a different robots.txt to everyone else. Which is what Reddit is doing here.
