update: I have confirmed with two Google employees that these new guidelines were put up by mistake and were not meant to go public yet. I just happened to notice them and I naturally wrote about them.
I have removed this post because I was writing about something that was not supposed to go live yet. I guess all I can tell you for sure is that there will be new guidelines at some point.
Sorry for the confusion. Not what I wanted for my first blog post on feedthebot!
