Not far from the original gameplay? It allows the spy to rest in different locations while hacking which completely disrupts a mercs ability to stop a terminal in line-of-sight from being hacked.
Using pirate room layout as an example: If a merc enters from the bridge from greek and spy is hacking under the bridge just out of range for the merc he could try to guess where he is by firing a nade against the wall, but if he has no nades he can't stop him for at least another 3-4 seconds.
I also think that a plantable explosive device granted to the spy is a terrible idea. Now let's pretend here and say you found a way to make it balanced, there's still the problem that a merc has no defense against an explosive he knows is around the corner. Spies have chaff and they can run in/out to set it off but a merc is completely helpless. And inserting some sort of a disabling device for a merc would be a waste of a slot when it only works in rare situations for a device that can't exist more than twice at once on a map.
I think it adds another layer of complexity to the game that really doesn't need to be there, and feels forced and unnecessary.
