Warhammer Fantasy tagging question

When is the Total War: Warhammer supposed to be used? Asking as it’s odd as OFC it was a lot of people (including my) introduction to the Old World so plenty of art has it’s tag that could equally just have the base Warhammer Fantasy one, it’s a weird gray area that should be cleared up.

It really should only be used when it's obviously a reference to the game. Like post #9416739 being all the High Elf legendary lords, or post #4779923 where the game is referenced in the commentary.

Outside of direct references, though, it probably shouldn't have the Total War Warhammer tag.
