From a story perspective it's huge part of his development in his training. Depending on what it is it could also be a big help for JNR/RWBY. For example let's assume it's a forcefield like Invisible Woman from the Fantastic Four. That ability has a lot of potential and could be used to toss bad guys, protect himself/others. A lot of other things but if you know FF you get the idea. If the bad guys are insanely strong Jaune could help even the odds along with Ruby 's SEW powers, the relics, etc.

It might have to do with his family having strong Semblances and since we haven't met them yet they might not want to show it. Personally I think it will be revealed in volume 6 finale against Cinder or even Tyrian if he investigates his interest. With all the build up I think the reveal has to happen during an emotional moment. Seeing Cinder trying to murder Ruby or Tyrian attack Ren/Nora could do that.
