Request: API to fetch all comments including hierarchy relationship

Hello,

I saw in another thread being mentioned that there is no use for API for real users other than bots. So wanted to voice some real API uses that I would be interested in:

1. When I post a new blog post, if I find it worthy of sharing here, it would be nice to mirror the comments I get here back on my blog post. I can imagine using API to fetch all the comments from a tildes thread, including the hierarchy relationship. The API would return a JSON with Markdown and/or HTML like the XML that Disqus exports (but JSON). When people want to comment on that post, they can come to tildes to do so, or if they don't want to create an account here, or if they don't have an invite, they can comment via other means that I have (Webmentions, Twitter, email).
2. Second use is make something like hnrss possible.
