We'll cross that bridge if we get to that point. I don't expect there will be a timeline reset or anything like that. I don't like the idea of doing that. I'd give the show a chance, but that's not my preferred path.I do wonder how folks are going to react if Kurtzman and company press a massive reset button after going on for two years that the show was "Prime"?
I suspect the show will jump to a different time and that resolves the timeline/canon thing--Spock has no sister. Starfleet has no spore drive--without resetting or overwriting the timeline.
