From a design philosophy and as a user, I would not want to see a "no-ai" metainfo in that box.
You also do not want to see a "not made with unity", "not made with rpg maker", "no touchscreen input", and so on.
Leafo called it tag, and it is in the suggested tag box, and it shows as an url modifier with tag, but it seems to be metainfo. Like "made-with-godot".
