Every so often if I’m feeling down I remind myself that Erid and Vulcan canonically orbit the same star, 40 Eridani A, ergo during the events of phm they shared a single Petrova line.
So that means Rocky and Grace are the historical figures who saved Vulcan from extinction.
Since Mary’s ship logs were dispersed and studied, I like to imagine that Vulcans think of Rocky and Grace with a sort of reverence. Maybe they have statues of them in the Katric Ark. In the Kelvin timeline, after the events of Nero, the old symbols and statues are resurrected on New Vulcan, this time with some new additions.
And that is how the city center of New Shikahr ends up having four prominent statues; an Eridian and a Terran who saved Vulcan’s planet, and a Vulcan and his Terran Captain who could not save the planet but managed to preserve Vulcan culture along with the Elders and save as many lives as they could which allowed the Vulcan race to avoid extinction once again.
Bonus HC: Jim and Spock argue for years over whether Grace was more prominently a ship captain or a science officer, both wanting to claim him as one of their own. Scotty always happily reminds them that the real hero was the engineer who saved him.
