DSE Super Gate still in-game?

[Wixelt]

Recently, whilst I was browsing Disco. related content, I happened to notice that on one of the older (now no longer there) Twitter accounts for Discovery, there was an image for what appeared to be a Super Jump Gate being worked on by Deep Space Engineering, along with some text that implied that it was locateable in-game.

Through various means, I have been unable to find out, so now that the forums are back up, i'd like to ask. Is that gate still in-game, and if so, where can I find it (I know it probably doesn't go anywhere, but i'm still curious)?
