Hardware cost+extra weight (need to make the glass thicker to be able to handle extra force and not push on the display). Turns out nobody was really using it because discoverability sucked..
Hardware cost & weight, fine. Glass doesn't need to be thicker than it currently is (I can press on my 13 Pro's screen about twice as hard as was needed for 3D Touch's max depth, and no issues with the screen), and the last time I replaced a battery on a 12, the screen was just as thick as the XS.

Sure, but then redesign the UI after removing 3D Touch to not be equally undiscoverable but less precise. Even on the latest iOS beta with its full redesign, there's still many, many actions that require a long press that are completely undiscoverable. (For example, if you don't have the Shazam app installed, go find the list of songs Siri has recognized when asked "What's this song?" Don't look up the answer.)

I dont think this is a great argument. The glass maybe needs to be thicker so the sensors on the border can properly measure the pressure, not because the screen is close to shattering.
He is capable of pressing twice as hard as the feature required at maximum. The screen handles 2x the maximum without issues. Therefore, the glass is thick enough to handle half that pressure,as required by the feature.
As far as I know, the pressure is measured around the edge of the screen. If the screen is thin enough, it could bend when pressed and the pressure applied to the center of the screen can’t be properly measured. I don’t think the problem with a too thin screen is the screen breaking when pressing it.
The discoverability sucked because Apple never rolled this out to all of the devices, themselves grossly under utilized the feature and eventually ghosted it.
It was by far the best cursor control paradigm on iOS. Now everything is long press which is slow and as error prone.
I’m all for proposing different paradigms as accessibility but 3dtouch was awesome.
3D Touch was amazing for typing alone, I miss it basically every day when I type more than a couple of words on my phone. It was so great to be able to firm-press and slide to move the insertion point, or firmer press to select a word or create a selection. It was like a stripped down mobile version of the kind of write-and-edit flow of jumping around between words that I can get on a proper keyboard with Emacs keybindings drilled into my brain.
You can still move the cursor by long pressing on the space bar, in case you didn't know. There's no equivalent replacement for the selection behavior you're describing, though (as far as I'm aware).
