Hitman, GTA, both of which use a non-raytraced implementation. More to the point, lack of mirrors doesn't impact the gameplay. It's something that's trotted out as a nice gimmick, 99% of the time it's not there, and you don't really notice that it's missing.
Hitman is an example that contradicts your point about gameplay, guards will see you in mirrors and act appropriately. They'll be doing that for gameplay with a non-graphical method, but you need to show it to the player graphically for them to appreciate the senses available

See:

Yeah, it's a nice detail for the 1% of time that you're in a bathroom or whatever, but it's not like the immersion takes a hit when it's missing. Moreover because the game is third person, you can't even accurately judge whether you'll be spotted through a mirror or not.
GTA V's implementation did not work in their cars. Rear view and side view mirrors in cars are noticeably low quality and missing other cars while driving, which is pretty big for gameplay purposes.
Working mirrors are limited to less complex scenes in GTA. Hitman too I believe.
