Have you ever not been able to start a car, or had a car stall on you and you have to figure out what the car needs to get going again? It's happened to me before, and these bugs with the crosshairs and recticles and such remind me of that. It's a nice little break in the game when your recticle disappears and you have to figure out how to get it back. Usually for me I either have to switch weapons, switch to my JAW, scope in with something with sights, or run and slide to get the recticle back or the crosshair in my scope to come back. It's kind of fun to have that little in game puzzle break, that and the cool glitch in parking lot where you can walk to the tallest point in the game then walk through a wall then off the edge of the doorway to the roof and float there, allowing you to move all over the map way above everyone else. That's kind of dope as well. Anyways just thought I'd throw in my two sense.
I like your mentality, but IMO, I like games to run well, and not worry about reticle puzzles. :p
