I don't think they dislike it, I think it's just not their own baby and not part of the modern canon (which is true of everything pre-Mega at this point).
Also if you want to be technical, you could argue they acknowledged the Orre games when they gave all ribbons the ability to give the Pokemon a title in Gen 9 (Scarlet and Violet).
Any earned ribbon lets you add a title to a Pokemons name, each ribbon has a unique one. There are two ribbons specific to the Orre games that are still recognised, and their titles are "the Triumphant" (for the National Ribbon which is given to anything that is purified in Colo/XD) and "the 100x Victorious" (for the Earth Ribbon which is given for beating Mt Battle in Colo/XD).
