It would be nice if both Space and Discuss could get a interwiki prefix so that it would be possible to make a nice internal link from a wiki here.
It’s in our ToDo list: https://phabricator.wikimedia.org/T226871
I’m still hesitant about creating an interwiki link before having a permanent URL (before bringing Space to production servers) maybe maybe it’s just me.
Why? Interwiki links don’t need to change when the site is moved; they are a lot less problematic than full links in that regard.
Any takers? You don’t need to be a Space anything to complete this task.
