I see. You have coined the term exactly, partial-reverse. Nice. You have also put forward a realistic question of 'why do we need'. Well, surely not everyone needs it and definitely it's not urgently needed, but its just the counterintuitive incompleteness such that 'it works for a whole, but not part of it', you see. About the gain, of course it's unlike a monumental speed boost, but its just a little spot that I saw lacking in power.
What I had in mind was the algorithmic cost to the program itself, not the cost in developing it. But now that you explained to me, I understand the situation.
