It is useful if the art pretty much centers around it. Taiji for example uses it all the time, it doesn't matter what part of your body makes contact with theirs, energy can be directed (and redirected) to that point in any direction. You "sense" the openings, so you would never use it unless there was no doubt you could. Real Taiji applications are quite brutal, because like all other internal arts, you are not only using your explosive energy, but you are "sucking them in" and redirecting their own force directly into your explosive force. Of course the more compassionate ones just redirect their energies away, but in reality, it should not be away, but into the ground (face first if need be).
Bagua for example, will allow you to use this type of energy from various angles, even ankward ones, not just linear ones.
