Their appearances were but mere cameos. If anything they might be shown to pop back up when the crossover resumes in January. Also, we all know that with everyone but the paragons being wiped out, that the 7 will find a way to mostly restore everyone. Meaning Lucifer's Earth/ the Titan's Earth will be restored no problem, and likely remain separate. But looking at Supergirl's Earth for example, all the regulars were shown to have made it to Earth-1. So they could restore/ or fuse Earth 1/Earth-38 into one single Earth and bring back everyone lost.
