For most of my connections, I don't care whether I connected the object 'from' or 'to' the other. I'd like to see when I'm editing a post any posts that are connected, regardless where the connection was made from.
Also, I'd like to be able to call a function from the API that returns all the connections without regard to direction. I know that the way that it currently works, I can just call the p2p_get_connected function twice, but that seems awkward.
Related, what if a connection is made both from and to? That seems like double effort.
