I think it's because people don't want to stretch the reality bubble too much.
By making a world in which the only totally unreal thing is superpowered mutants, then it's more grounded than if everything in that world is sci-fi.
It's a good point for debate. A mutant who is able to time travel might be one way to do it. On the other hand, a machine might work as well, since they already have Cerebro and Magneto's mutant-making machine from X1.
It could go either way. Looper managed to incorporate a time machine with no explanation at all; it was just a MacGuffin. But they might do something different.
