Wifi 802.11ac - Is the IEEE staffed by morons?

Really? With all the letters in the alphabet, did they have to use 1) two letters and 2) have the first letter be the same as an established Wifi protocol (i.e., 802.11a). I would hate to be in tech support and get all the calls asking me to explain why 802.11ac routers are awesome and 802.11a/g routers suck horribly.
