Yes, that's a good point about RSS.

I think federated features (such as comment threads) would have to be dynamic -- perhaps handled by a separate server affiliated with the site.

I'm wondering if this is the niche that customizable servers like "Streams" or "Emissary" is targeting? Or perhaps it could just post to a small server, like GoToSocial or SNAC? IDK. 🤔
