I actually lean in the opposite direction. Seeing so much discrimination against small developers using AI, I would rather mark my game with “AI” tag even though there is (probably) no AI content currently in game, both as a show of compassion and to avoid any backlash if I do use AI in the future. The reason I say “probably” is that since practically every modern graphics, sound and code editor uses AI heavily, by applying Photoshop filter or googling some API call or rare English phrase I have possibly “contaminated” my game.
So in practical terms, I would like to see additional “Some AI may be used somewhere” tag, for neutrally-minded developers and users.
