Interesting finding. Since I don't have an 802.11ac AirPort to experiement with yet, I do note that the Radio Mode option (in the latest 6.3 version of the AirPort Utility) still exists with the earlier 802.11n models.
Apple claims that the new AirPorts are backwards compatible with all of the radio mode standards but I have to admit it appears odd to have removed this option when only 802.11ac models are present.

Despite the warning that it may not work with the new Extreme, I used Airport Utility 5.6 to set up select the radio mode I wanted for bridge mode. I pulled out a 5th Generation Extreme, and plugged in the 802.11ac Extreme and everything seems to work the same. Do not have any 802.11ac devices yet.

Will the ac give more range and throughput to 11n devices such as a 2012 classic mbp? Were in a large hourse with the router upstairs about 100 ft away from our tv and where we use our devices. Can change that part. Just curious if the new 2013 extends range for the 11n?

The newer antenna design of the 802.11ac base station should provide additional range/performance over the older 802.11n models ... but remember that this is a two-way street. Both the transmitting AND receiving antennas would need to be improved for an overall performance gain. By that I mean older wireless clients may "see" a stronger signal, but may still have difficulty communicating due to the limitation of their built-in antennas.

I had a different result (if I understood your comment correctly). I launched Airport Utility 5.6, accessed the AEac, option-clicked radio mode, selected 5ghz n only/2.4ghz n only, and selected update. After the restart, the AEac remained in automatic radio mode.
Seems like selecting custom radio mode options for the new AEac does not work.
