Any plans to include more Joints for Rigging to get more Precision?

At some points, we need to rig a Dwarf or a Troll character. Or there are some characters that is hunchback, etc. Thus, when we rig such characters, there are some unwanted results in the rig in current automated rigging process. 

In my opinion, if we have additional joints (neck, tail bone, etc.) which can be included in the list by clicking to "advanced" option, that would create extra precision. For instance, I am trying to rig this troll character and its face is in same level with its neck. Therefore, if I could tag where the neck and chin are from side of the character, I would be able to rig the model flawlessly. But currently, it rigs with unwanted results. 

Hope this can be fixed.
