I just sort of assume that there will be a twist. I'd be more surprised if there wasn't.
That's a very different situation than all the X-Men themselves knowing. Actually Charles and Mags only know because Moira says so (with TP of course). The rest of the X-Men are relying on Chucks word, which has a history of him putting all kinds of spin on it, backed up by Mags of all people. You can't tell me there's a single senior X-Man who would take that as gospel at this point. If so who, and for pity sake why?

During Secret Empire where Hydra took over North America, Captain America told Emma Frost to keep the mutants out of his realm, and gave her California (New Tian) with the agreement that the mutants could not leave New Tian into Hydra territory or be executed. Emma still joined the resistance against Hydra and personally worked to defeat evil Captain America.
We are MUTANT..Krakoa, FOREVER!!! “Liberté, Égalité, Fraternité”
Didn't she hand over the Mcguffin Cosmic Cube shard without a fight, and only joined in at the last moment when the tide turned against evil Cap? Did she actually work with the resistance before then? And did any mutants work with the resistance? All I can remember is some mutants antagonizing the Secret Warriors for being a bunch of Inhumans.
