The species-wide telepathic link with destroyed planet was pretty extensively explored in New Who fandom (where the species-wide telepathy was already more or less established canon, and the tailspins of the survivors were pretty bleeding obvious.)

I don't know whether the idea that's been showing up in Reboot fic is bleedover from Who fandom, or if it's independently generated out of similar circumstance, but I can't see it in ST fic without thinking back to DW.

Vulcans' telepathy is hard to figure out anyway, though, because we've got the Romulans - the last set of a few tens of thousands Vulcan exiles - who've somehow managed to lose the ability (which was fundamental to their biology and culture) in just a couple thousand years. There've been a bunch of different explanations of why and how that happened, and I can't help but wonder if some of them will apply to the last Vulcans, too.
