Uta is confirmed to be canon in the chapter

In the part of Shanks, some vignettes of memories of her past are seen, and in one of them, the silhouette of Uta is seen in shadows (you can see that it is Uta because you can see her hairstyle).
It's an interesting detail because if Shanks remembers Uta, the character becomes canon in the Manga (as is Shiki). And if that is so, it would be necessary to see if Uta's relationship with Luffy as children is also, or if she can be an important character in the story as she is the daughter of Shanks.
Obviously the history of the film would not have to be canon (as Strong World is not) but her past could be (as Shiki's past) being linked to Luffy.
