I don't know how this applies to US code or what (can't see an issue with it), but I will tell you what they do in new houses up here where I live...
They will run 8/3 to the stove, and 10/3 to the dryer location. If you tell them straight out that you have gas appliances (either or both), then they will cap off one hot wire, pigtail the other hot and a neutral to #14s, and put in a 15 A receptical. Then, in goes a 15 A breaker at the panel.
(In the case of the dryer, this is *in addition* to the dedicated laundry circuit.)
It's easily reversable at any time because the wire size is correct. It would just require changing the receptical and installing a new breaker.
