They both approve of each other, for sure, but they don't actually demand crossover.
Didn't Y'shtola tell Zero at the end that they plan on restoring life on the 13th? The quote was "[...] Which gives me cause to hope there may be a way to restore Light and life to the Thirteenth." And then Varshahn continues "Restoring the Light would serve our efforts to find and free Azdaja. There is no reason not to try."
So yes, I think the MSQ also has plans on un-Voiding the 13th at some point, at which I think it would be odd not to mention Unukalhai. Maybe they'll make two slightly different variations of the cutscene - one in which you know him (if you did the Warring Triad) and one if you don't. I think this would be the first time they ever did this though but it was only a matter of time considering how many of these important sidequests we have.
