I was not a fan of introducing legacy characters like Spock, Kirk - and even lesser-explored characters like Pike, Chapel, Number One and M'Benga to an extent - in DIS/SNW. Introduce new characters I say, that aren't hamstrung by what's already been established - something that I think is even more important in a show that's set in the "past".
That said, if we were to have a pre-TOS Spock, I wanted to see a Spock who would credibly grin at a plant or exclaim "The women!". I think SNW has given us that.
However, you're absolutely right. The destination for the character in SNW is for him to choose his Vulcan half over his human half. Hopefully the writers have planned this out. There's potential for a poignant story arc here, not just for Spock but also Chapel and T'Pring.
