If Section 31 are the bad guys, and even the ex-Empress herself finds that she has to sort them out/set them straight/shoot all of them, great.
If Section 31 are Hard Men Making Hard Decisions and essentially "the good guys", absolutely kill me now. That is literally, I do mean literally the antithesis of everything, absolutely everything Star Trek has stood for, for decades.
I mean, if it's the latter, hopefully the next series of Doctor Who can feature him as square-jawed, musclebound slightly-dim American man who subscribes very strongly to "Shoot first and ask questions later" and just absolutely blasts his way through every problem. But he has a natty scarf on so it's fine!
