It's been a while since I played it, but to me the fact that he'd gone back to get the crystals he seeded implied that he had already destroyed those worlds, as he was about to do to the FF4 world before he was stopped.

It's just a more fun way to view the series to me.
Handwaving explicit connections as "just cameos" to shut it down doesn't make much sense to me.
Pupu is another connection. There's also the "word of God" on VII and X sharing a universe, so why not all of them?
It makes it less fun to other people. And also if you try to cram all the games into one universe, you wind up with irreconcilable paradoxes. We already have the Interdimensional Rift connecting them via a multiverse; why isn't that good enough?
