Jack Thomas specifically said there are "Easter Eggs" for the older fans to find. Some may argue that easter eggs are not, uh, canon, and are really just there for fans to notice. The same happened with Mildew in RTTE: we see a soldier in Drago's army whose appearance was later confirmed to be a "Mildew easter egg". Of course, the absurdity of him joining Drago and the use of "easter egg" immediately made fans discard the statement. The same may be true for RR. They make references and mentions of all the other species, but as long as none of them make an appearance and have a mention of their name, it may just be that. A reference that fans can delight on when/if they find them.
