Is 3D Touch really a thing ?

I don’t think so.

I mean, to me is definitively not something that really changes the way you interact with your phone, well, it does if your interaction is with an iPhone, but in android we have something similar, the long press witch helps you to achieve the exact same thing. 

There are some other gestures like the double tap and swipe up/down in chrome to zoom in and out. So for me not something that useful, new yes, valuable yes,  useful yes, the thing…. No.
