If it was truly irrelevant, it wouldn't need to be removed, and you wouldn't care.
You want it removed because you know that a non-trivial number of people don't want to play AI slop. You'd prefer to decieve than be transparent and let them make their own choices. Disappointing.
Agreed. The AI tag is relevant to art exhibits for authorship disclosure, and to digital content licensing marketplaces where buyers need to understand the rights situation. It makes no sense for game stores, where AI will be involved in nearly all future production.
