I'm not sure how it was in the main game but I guess it could be done if the overlay was toned to the minimum and maybe the enemies would just be outlined.
As for the nades, shame, guess other things can be tweaked instead. The issue is you can't use them fast because there's just no going around the 5 second timer, so it's harder to punish the enemies that group up on a staircase or something.
MM made it look easy, but generally Hidden's fucked on maps like Docks where he can't even hide out of IRIS's sight completely.
