It will look cool, which is reason enough to use it. That being said you may have players which only sell them from Credits as opposed to using them.
Expendable Camos can continue to be used for rewards, but their "value" will be less than current as they won't contain economic or gameplay benefit. That should be able to be factored when figured how much/how many to offer as a reward that is interesting. Again, they could be sold for credits should a player not choose to wear them.
