For the most part, sockets seem to be treated similarly to bones. For example, to get the location of a bone, you use a ‘Get Socket Location’ node, using the bone name in the socket name field. Hence, it’s strange (and unuseful) that entering a socket name to the ‘Get Parent Bone’ node returns none. This request is for this behaviour to be changed, so that the socket’s parent would be returned instead if a socket name is entered.
