The things you mentioned are backend dependant, though, not intrinsic to how you render and present them.
What specific aspects of facebook's comment section under post make it that json response is so much better then a html one?

- the social graph underlying every post and content producer (one of the reasons FB introduced graphql)
- the recommendation and advertising algos that are interdependent on the content feed
- the realtime “fire hose” nature of the feed integrating a huge number of disparate data sources
Again I don’t like FB the app and I’m not on it. But even its core product is vastly more complex than a forum.
FWIW I’ve developed social networks and forums professionally; social networks are inherently more interactive. My first real exposure to front end dev was when I worked on a social network. If I had to build the same webapp today there is zero consideration of writing it as a backend rendered application or restricting to only progressive enhancement. It would only put off the inevitable migration to real FE tech.
