Will Warbot get another phase?

[-Variant]

So, figured I'd make a thread real quick.
Since some point in the beta, WARBOT has had an extra phase that seems finished, but is currently unused.
There exists animations for a 'summoning' phase where the Warbot kneels down and starts sucking. The anims are all finished, and they even have entire audio/sound sets for this action as well.

I'm wondering if this is scrapped, or possibly coming later? Maybe for Warbot refights? I'd love to have another phase added for repeat kills. (Though with rewards to make up for the added steps.) I'm mostly just putting it out there to query if its been scrapped or not. It seems to resemble the concept art "Gestalt Bomb" phase, I'd be interested to know what it might've done if implemented.
