I think it's not a problem of terms, it's more overall gameplay issue of too many confusing mechanics. I don't see any reason for non-unique persistent buildings, so if that's so, I think it's better to just scrap the term "persistent" and use "unique" instead.I'm still not getting it.
If you tell me that a building is unique to a civ, you have already told me that it can only be built in the time of that civ, haven't you? Why does it need a new and confusing term? Firaxis is calling them both Unique and Ageless, but one of these is redundant, isn't it?
Can Ageless buildings be replaced? I thought the point of both terms was to convey that neither could be replaced?
Edit: so that is probably what I've missed - the granaries etc. (whatever term they're using) can be replaced but their effects persist, they don't become redundant in a new Age. Still think you can signify this with one tag though.
BTW, I don't remember seeing "persistent" in UI. "Ageless" is surely there, but I think "persistent" was only mentioned verbally and could be some internal term within the team, not appearing in game.
