Thanks Luna, now would be a good time to go back to the original intent for the topic...
At the very least it makes sense for such power to be wielded by Luke Skywalker and his son, but Oneness isn't exactly something we can use as an example - as was mentioned, it wasn't a common thing. We have to assume that the average Joe Jedi who uses TK has a normal level of Force sensitivity... not everyone can be a Kyp Durron or Anakin Skywalker, after all
I still maintain that TK has the potential to do just about anything, but as Relmeob said it would be something that would need to be trained. Not every application is practical, and many are not easy for someone without special training. How many folks do you see using the Force for flight? Not too many, even including powerhouses like Luke or Anakin.
