I avoid this issue by completely ignoring the v2 timelines.
v1.0 is the original, and the one I grew up with. I left the country in 1987 and didn't even know there was a second version until about ten years ago. I can't imagine why anyone whose originally exposure to T2K was with v1.0 would willingly use the v2 timelines.
IMHO, the timeline didn't need revamping. They should have declared it an alternative history game, instead of trying to rehash it around RL events. But, that's just me.
