Replacing the discussion system

Feature-wise, is it possible to link to a particular reply in a thread with DiscussionTools? I realize it might not be the most important feature, but I remember using it a few times here, and it was handy. (It's nice not having to dig history to find a diff corresponding to a reply).

Not currently, but it's a planned feature: https://phabricator.wikimedia.org/T275729

To be exact: it is possible, but there is no UI yet to get the correct ID. If you happen to know the ID (e.g. using the user script described in https://www.mediawiki.org/wiki/Topic:Wmredg44lh8v9x9i, or using the browser developer tools), you can already link to it.
