And as I said, the manga is supervised by Horikoshi himself, he would already have the time skip in mind when Mission 2 was released (there isnt a huge gap between Mission 2 and Chapter 257)

Also, despite what I believe, I don't treat it as canon. My theories are mine and I don't write them on the wiki. But TUM it's still official, just like filler episodes and OVAs.
