Certainly its too early to even speculate on that. Feasibility is the primary concern.
Of course in the end it would depend on what would the process require and what would it generate. In my opinion as long as the outcome is EM and there is more of it than input Q>1, then you can make it useful. On the other hand if the Q is too high then it is much less desirable.
