New Question about Ash’s reserves not in To Be a Pokémon Master

I knew that Ash’s only eight reserves that are not physically in any of the To Be a Pokémon Master episodes include Noctowl, Torkoal, Gliscor, Gible, Lycanroc, Melmetal, Lucario and Dracovish ever since their final physical anime appearances. So do you think that they’ll make their own comeback as in any of their Trainer Ash’s post-retirement anime episodes? Why? Please let me know, thanks.😉
