Maybe a less popular one, but all the stuff Admiral Vance had to do to keep the Federation together prior to Discovery’s arrival. He’s pragmatic and you can tell from how he treats Stamets in the s3 finale he’s no stranger to sacrifice. From his discussion with Osyraa, though, you can see he’s still committed to the high-minded ideals of Starfleet and the UFP.
A movie about Admiral Vance's pre-DSC experiences would be great.
I'd like to see a mini-series about the immediate post-Burn crumbling of the Federation. Tied to how, while much smaller and muted, the Federation still went on.
