However, in the years following its completion and even more so since the release of 'Super', there has been debate over whether 'Dragon Ball GT' is canon within the franchise. The short answer is: it depends who you ask. In 2005, for a DVD anime series box set,
Akira Toriyama himself defined 'GT' as a great "alternate history of the original 'Dragon Ball'", questioning their status. However, Toei Animation (the animation studio behind the entire franchise) and Shueisha (the publisher behind the manga)
recognized 'GT' as an official part of the canon in the timelines presented at the screenings.
In 1993, Akira Toriyama entrusts Takao Koyama with the new story of the little robot and for the designs he chooses Katsuyoshi Nakatsuru (creator of SS4). That manga is titled "The Return Of Dr. Slump" and is the official continuation of the story that ended in 1984.

And now the big reveal begins!!!
As we know, Arale is considered "canonical" within the story in Dragon Ball. That's because Arale appeared in the Dragon Ball manga helping Goku and in the anime dbs
Because in one of the chapters of the sequel to Dr.Slump, Goku makes an appearance, but surprisingly, he's Goku from Dragon Ball GT!
You read that right, Goku from Dragon Ball GT made an appearance in the official sequel to Arale, remembering that Arale shares the same world as Dragon Ball
I propose that the GT line be built into the Dragon Ball cosmology, as a separate timeline, like trunks timeline or something like that, it won't change much, it will just exist in the same shared multiverse, as a separate line, like Future Trunks, and that's all.
Edit, edit: according to this site Akira toriyama made a contribution to GT, every interview here
