Well, that's the thing. In TOS, stuff like mind melds and Pon Farr were treated as surprising brand new discoveries about the Vulcan people. Now with them being commonplace on prequel shows like SNW, now it just seems like Kirk & McCoy were either unusually thick or spectacularly forgetful.
I get this, I really do, because you don't necessarily limit yourself based on a bits of dialogue on a 60-year-old TV show, but at the same time, it bugs me that it's been the default on Trek shows since at least the 90s to just write over & contradict TOS whenever they can. (And sure, there's some stuff like "Women can't be Starfleet Captains" and "Robert April was a white man" that I don't mind them changing in the least.)
But continuity stuff that they could easily adhere to if they wanted to, like "Spock has never performed a mind meld on a human," or "Humans don't know about Pon Farr," or "People on the Enterprise don't know about T'Pring," or even "Spock doesn't freely share his feelings with people, especially not a documentary crew"... All of that is thrown out for little to no reason (IMO).
I mean, at this point, we could have a flash forward scene of 2267 Spock going, "Oh shit, KHAN Noonien Singh! Just like my old hookup La'an Noonien Singh! Wow, I really should've made that connection before. Geez, even their names rhyme. ...Hey, Scotty, you remember the Enterprise's old security chief?"
