Why Does the Auction House Mount Not Have Mana Food?

When you spend 5 million gold on an auction house mount, you would think it would come equipped with everything you need in game to survive. But for some reason, while Merchant Maku offers a wide variety of food that restores health, you cannot purchase vendor food that restores mana, such as Rockskip Mineral Water.

We didn’t see it added with 8.1.5, so there is hope we might see it with the Rise of Azshara content patch 8.2. The ability for healers to grab mana food off a vendor mount when not an an innkeeper or when there isn’t a mage available is annoying.

.@WatcherDev @WarcraftDevs Can we get some healer love by adding some mana food/drink to the long boi mount vendors? For 5m gold, I should be able to indulge in all my mana needs from Merchant Maku (especially for those oh crap, I'm out of mana food moments).
