Namco does have to be careful with it though, especially for exclusivity specifically for battle passes. Battle passes had also been a thing since the PS3/360 days, and majority of them back then have been expired or cannot be accessed because the specific game server is closed for good. Actually there are even battle passes for games on early PS4 days that are no longer around.
Ex: if you play Tekken 8 10 years from now (for any reason), there would be some items tied to battle passes (usually like in other games) that are not hard drive bound, but server bound (games like Call of Duty or something similar to Genshin). Meaning that if the server of that game is closed, you won't have access to those items because they were server bound. I don't have Tekken 8 so maybe someone could provide context on how Namco is doing it.
