The Ailea Meteorite was such a huge event, that it warrented it's own alternate universe where it doesn't exist. It's also possible that the meteorite was the source of Keshin as well, if not the direct cause.

I don't think we would ever get as far as GO unless they decided to change Tenma's age as well, similar case with what they did with Kira Hiroto as well since he was the older brother for Hitomiko in the original timeline but is the younger brother for this timeline. If not, we could expect Kid Tenma to show up somewhere as a cameo.
