Is Internecivus raptus still a thing or has that been retconned as the USM's name for the species? I see no reason why the two designations can't co-exist, but I'm sure we can find a way to turn it into a debate.
As for those cutaways, Ms. Perry just told us that this book was written a few months after the events of AR. Does that old USCM hardware still exist? For that matter, does the USCM still exist? I'd have thought the USM would have absorbed it long ago.
