Agreed. These services offer a lot of valuable social infrastructure, and it would be nice to keep the good and stop the bad.

On a personal level I do something like this on my home router by adding latency to specific websites and I totally recommend this to anyone trying to cut the habit. A few hundred ms of extra latency can really kill the doomscroll’s grip while still giving you access to messages from friends. Doing this is also not too hard to configure using a pi hole and some vibe networking.
