Dude, of course you didn't mention it. That's because it involves specific intensive programming that rules out the dualshock for newer games, lol. Devs are not going to double back and try to reprogram dualshock compatibility after they've already specifically supported the dualsense through extensive development. That would be ridiculous.
And you completely misunderstood what I'm saying about controller compatibility. It doesn't justify lack of compatibility as much as it is a non-argument. Like I said, the haptic feedback feature alone renders the dualshock incompatible with new programming using the dualsense. This is a new console, with new controllers and a ton of new tech involved in both. The only reasonable thing to do is what Sony has done, which is allow old controllers to work with old games. Regardless of people expecting or not expecting support for said controllers doesn't matter; the new tech rules out that support for next gen PS games.
You are literally shooting aimlessly from the hips. "intensive programming". 😂🤣
If you use a DS4 for a Dual Sense game, the DS4 simply wouldn't support the features of the Dual Sense. Its not that complicated. It doesn't matter which side of the bench you want to be on but lets not make shit up just cause.
