Oh boy, I'm sure glad that it's now official, thanks OP for declaring it so. Any other official declarations you'd like to make?
Dunno about the cache but I'm ilvl353 and I still have a 325 azerite chest.
That's right. I can ONLY find azerite helms. Like a curse. Cannot even craft a cheap 340 chest or get one off the AH since it's azerite or empty slot.
