So it appears that there were a good number of complaints about the feature, I'm guessing unwanted Notification panel activation. From the OEM perspective it must have tripped the threshold and they did away with it. Had they left it with the rationale that it can be toggled off, they would have still received the same number of complaints and would have had to tell the user to turn it off.
If it were me, I would have done the same thing or hidden it in Developer options where most people wouldn't find it.

You can ask for this feature to be added again through the Samsung Members app Support tab at the bottom. Find Send feedback and submit this as an Error report. Hopefully, Samsung can bring back this functionality in an update soon. In the meantime, I recommend checking out Samsung's Good Lock app. Within it are many modules you can install that enhance the personalization and functionality of your device. Specifically, the RegiStar and MultiStar (I ❤️ Foldables option) modules have some options you may be interested in. 🙂
