Okay, guys. Look at it this way...
1. The books are adaptations, set in different universes.
2. The extra stories are bonuses within the same physical book.
3. The bonuses don't contradict either the MCU or the book's timeline.
So, when you say that the extra stories don't contradict the MCU... well, they also don't contradict the book that they're physically linked to. Wouldn't it make sense to assume that the bonuses are set within the continuity of the adaptation rather than the main reality?
Though, honestly, I'm fine with including them anyway.
