There are two threads (heh) of work on threading in Matrix - one is label-based threading like Zulip: https://github.com/matrix-org/matrix-doc/pull/2326 https://github.com/matrix-org/matrix-doc/pull/2326, which is implemented today in Synapse but isn't exposed by any(?) clients. The other is full HN/Reddit/Twitter/FB style threading, as per https://github.com/matrix-org/matrix-doc/pull/2836/files https://github.com/matrix-org/matrix-doc/pull/2836/files, which has been implemented at https://github.com/matrix-org/cerulean https://github.com/matrix-org/cerulean and if successful will get fast-tracked into Element. Quite what the UX will be is unclear, but it's unlikely to be Slack/MM/Gitter-style.
