No, this isn’t in the Discourse roadmap.
Also, this will never be a Discourse feature. It’s a bunch of parsing rules that lives in Telegram servers and must be submitted to their team for approval. And it’s a by domain thing, so every Discourse site would need to be submitted/approved.
So what someone from the community can do is create the rule for a topic page, and share it here on Meta so people who are interested can submit their sites using the same rules.
