I wonder if this element of Spock's past could be a Strange New Worlds plotline:

Kind of depends when SNW will take place, the Discovery episodes with Pike and Spock took place around 2258 while Spock and Leila's romance was around 2261 (Still when he was with Pike, Kirk didn't take command until four years later).
