I personally consider everything that we've seen so far to be canon. Sumire's arc was a novel which means it wasn't pulled out of nowhere plus the fact that revolved around the Nue and Boruto's Jogan shows that it is definitely relevant to the story as well as it being relevant to the Otsutsuki clan which are going to clearly be the main villans of the whole "Boruto series". The Gaiden arc was obviously part of the manga. And since this Mist Village trip has been mentioned by Boruto in the current chapter then it's probably a reference to it being relevant to the current story line. Plus the new 7 ninja swordsmen that we have now are so well thought out design wise for them to just be filler characters. I pretty sure those who will stay alive out of them will definitely make an appearance in the manga.
