Same logic really can go for potions too. They are so marginally useful, having 99 isn't really going to break anything. I promise you'll be dead before you can use them all if you happen to find yourself in the rare situation in which a potion/ether is needed.
They could easily fix potions and ethers with a global cooldown to prevent spammage anyway if it became a problem.
