I hate to bring it up - it's not weird enough to be interesting - but
"We have seen only that Godric left his Sword to the defense of Hogwarts, if a worthy student ever faced a foe they could not defeat alone."
Harry first heard of this sword
"Where Salazar and Godric and Rowena and Helga once raised Hogwarts by their power, creating the Locket and the Sword and the Diadem and the Cup, no wizard of these faded days has risen to rival them."
in the context of three other artifacts. As far as we know, he never learned anything else about the Diadem, but that may change now that the castle is handing out quest items and Harry faces a foe he can't defeat alone. I'd call that line another point in favor of the IA hypothesis.
I'm really surprised Harry hasn't come across the diadem in his studies (though possibly he did, but dismissed it as mythical). It seems a plausible way to brute force the magic system. E.g. Put on diadem, reverse engineer diadem, make better diadem, repeat. And make every other problem easier.
