Now, is there any statement if the novels are "canon" in Kubo's eyes? Has he said they are part of his story or not? Kubo's named as having co-written and illustrated We Do Knot Always Love You and Can't Fear Your Own World, so that alone seems to indicate that he considers them canon.

This discussion gives me flashbacks of Naruto wiki's similar debate regarding the publication of light novels not (solely) written by Kishimoto and whether to consider them canon - although the acceptance of them was helped by the fact that the ongoing anime ended up adapting some of them.
