I would rather agree with you. 
The proposed list comes from case studies where it was found to be useful. If for other cases the lines you propose are needed, we should add them. 
I also agree that there is a danger of strong inflation here...

In the studied case, the table contains two columns, one for the classical Tisserand Parameter (related to Earth, if I remember well) and another one related to Jupiter.

I also agree here, may be for next round ?
