Whether they are fixed or not does not determine whether they are legitimate or not. Shifting went a long time before it was fixed, and then the fix had to be undone because of grenades, and then a long time passed before it was fixed once more. IT was an exploit that entire time.

Peeking is, and always will be, a glitch in the geometry of the game,a nd players who peek are exploiting that glitch - they are exploiters.
