I thought 3D Touch was cut because no one seemed to know the functionality existed, it had a discoverability issue. It was kinda tacked onto iOS unlike WatchOS where it was part of how the entire OS was designed.
Which I always found unfortunate, it had some really nice uses like not needing to wait when holding down for the OS to register and being able to pull up a context menu, slide up, and release to select the menu item all in one motion. I was sad when it was removed, but I also get it.
I get the idea of a physical trackpad, and I do remember when that was the thing. I honestly don't even notice that the trackpad is not physically moving. It simulates the feel enough that if I didn't know it was not moving I would think it was. You are right it is shocking when you try to use it while it's off and it's like... oh right. But I just am not in that situation often. (However when Mac freezes and it "clicks" multiple times since it did not properly register ealrier, that's honestly kinda wild... but infrequent).
But I also like not needing to think, I need to press on a specific part of the trackpad for it to properly register. I vividly remember only the bottom half really registering and the higher you went the shallower the press was.
