Your attitude is correct, but in reality it didn't happen that way.
Nothing was removed at 60 apart from the PvP titles. Nothing was removed at 70 bar the Amani Warbear original. In Wrath? A couple of proto-drakes before they changed their mind further down the line, ToC tribute rewards and a few titles. Cataclysm only removed a FoS.
Gladiator mounts and R1 titles remain the most prestigious, even if many are wintraded. 90% (made up number but you get my point I hope) of Scarab Lords aren't legit. The vast majority gotten through gate bugs and new realm xfers.
The point I'm making is, bringing them back is not meaningless because all the stuff they are bringing back wasn't removed at 60. It was removed at 70.
