I went through the umpteen stages of grief reading this thread. I had a deposit on a 2023 Raptor and the truck finally arrived and is on its way to me from the dealer right now as we speak. I had agonized over a F-150 or F-250 Tremor vs a Raptor and ultimately went with the Raptor because I thought it had the Torsen in front like the Tremors and even more features. A Torsen front diff was was a must-have option for me on either the Tremor or Raptor. My previous F-150 never left me stuck in all manner of ice and snow even though it didn't have a front limited slip, but I wanted the best traction options possible for my new truck.
After going through this thread and then checking a few places, I think it has indeed been deleted from the Raptor with Ecoboost when they dropped it for the Raptor R in 2023. However, after getting to the end of this thread and then searching around, I think this was intentional after finally coming to grips with it.
It's mentioned in the video here that they no longer believe it is needed for the Gen3 Raptor:
Why were specific design decisions made with this brand-new Ford Raptor R? We chat with the truck's chief engineer to find out.

The Raptor didn't really need an additional 250 horsepower, but we're glad the truck got it.

Given the well-watered state of the dunes, indulging our juvenile urge to throw sand required running in rear-drive mode. Which is how we discovered that, in addition to the electronic locker, there's a brake-based limited-slip function for the open rear differential. The brake-based system works when one side or the other experiences a flare in wheel speed, and the brake on that side gives a squeeze to send power back to the other side. This system is operating in the background even when the AdvanceTrac stability-control system is completely disabled. So if, say, you want to roost some dunes in two-wheel drive, where the rear locker can't be engaged, the rear brakes will be getting a workout."
After I calmed down, I realize the truck is probably going to drive just fine in snow and sand. The Land Rover line is renown for having incredible traction in all conditions and you pay a premium for a Rover just to get their electronic traction controls instead of driving a Jeep with locking front diffs. I never missed having a locking or limited slip front diff in a Rover because I knew it had the fancy computer that was designed for an open front diff. Seems that Ford is now saying they have a similar system on the Raptor.
