True, I suppose I was largely focused on the fact that the isolated Romulan people would have been a more interesting follow up on the Typhon Pact's politics and the first true stress test for what was never supposed to be the Legion of Doom but a Warsaw Pact at worst.
The Pact was really meant to be more like the early Federation, a loose alliance of formerly divided cultures recognizing a common cause and struggling to work out their differences and find a path forward. They were meant to be an alternative to the Federation, not a black-hat enemy for it.
And yes, it could've been an interesting story in isolation if the novels had done the supernova. But I don't mind that things worked out the way they did, because PIC's reworking of the supernova premise makes so much more sense than the movie version, so I'd rather do fiction based on that continuity, given the chance. There are always missed opportunities in the past, but I'd rather focus on the opportunities that still exist.
