Bounce lights and the light gem:

It should give mappers some more freedom with lighting their map without punishing the players for it. It's of course a delicate balance, mappers shouldn't go too far with this so that the mismatch between lighting and lightgem becomes obvious.

We could argue that players seeing the light with their own eyes would assume they will have to stay out of it. I'd say it might be rather frustrating UX to never know if a light is going to tag you or not. I mean, it's the ultimate goal here - to let player through but the player themselves has no way to know if the light in front of them is decorative or not.

In practical terms it's not that simple though. When you use omni lights to to fake light reflecting off surfaces across the room, their radii can overlap somewhere "in the air" without hitting any visible surface, and be large enough to hit the player light detection cone or whatever is used for lightgem calculation. It can look weird and erratic ingame. And having such tool isn't uncommon practice either. Even Thief Deadly Shadows had a LightWeight parameter, which was a multiplier IIRC, so you could decide how much it affects the lightgem.
