The point is they won't skip it. They'll look at every aspect that could be expanded and they will expand it to milk as much content as they can out of it. And I will enjoy every minute of it, because I'm not a pessimist like some people.
A sidequest you're forced to play because it's actually part of the story, but yeah. As much as Cosmo Canyon or obtaining Cid's seaplane (as you later find out you could have just been breeding chocobos to reach the Temple), it's really just a sidequest. But they could easily (and likely would) re-write the Dyne events to be more relevant to Sephiroth and Jenova. It's already low-key relevant to Avalanche and Before Crisis.
