Yeah THIS is something I'm upset about. There's no reason to remove watchtogether. Leaving it in the website is just a distraction.
And while this article namechecks JellyFin. It's not really a solution. Because the primary purpose doesn't work there.

It's kinda stupid but I spend a lot of time stream syncing with my sister and she's in the room down the hall from me. I watch on my Firestick attached to one of my monitors and she watches on her laptop in bed. It's going to be very annoying to not able to sync watch.
