The problem is, that the new meta tag is not a true meta tag. The ai tags existed before as regular tags.
What I call meta tag is everything not added to the tag list by selecting tags and genres. You can have 1 main genre and 10 freely chosen tags.
The ai disclosure should not appear in tags at all in that info box. There should be a separate entry. Like "made with". And that should appear only when there is information available. Like "made with". You do not inform players that a game was not made with Unity. For assets that might be different, but it was said that assets without disclosure would be delisted after a grace period.
We shall see how this works out and gets changed over time to be a usefull feature. You currently cannot filter for no-ai-assets, only positive for graphics, sound, story, code. Some people would like a general no-ai, but others's might want a no-ai-assets filter, since there is mandatory ai disclosure for assets. Story and code are not assets. And code is not content. And some people might want to avoid ai narrative, but would not care for the other things either way.
