In terms of gameplay mechanics, old school zoom aiming achieves the same thing as ADS. Is getting to press your nose against virtual firearms really that important in a game about shooting werevolves and vampires?
I blame this on the proliferation of Call of Duty over traditional scifi and fantasy shooter franchises. You can fucking ADS on an assault rifle in Halo now 
This is the
equivalent of those insufferable “drums are never animated correctly” videos. If the gameplay is engaging and fun, I don’t care if the serial number on the gun you can see for three frames doesn’t match the numbering system that manufacturer uses.
Drummers can move faster than 20fps who knew?
