24 volt?

I put in a deposit on a HW last fall, so it will be a while before I can actually start building, but I'm thinking/dreaming about the myriad choices to be made.
Here's one I haven't seen discussed: I've seen that the Rotax 915is and newly announced 916iS are available with either a 12v or 24v electrical system (starter motor, and generators). I've never seen anyone discuss building at 24v Sling, but I wonder why not. The Cessna 172 I learned to fly on has a 24v electrical system. It looks like the 24v version's generators produce 800w, compared to 400w for the 12v system (which is the same current at double the voltage). If I understand that correctly, I think it would be pretty valuable.
For sure the battery would need to be 24v rather than 12v. What would be the implications on things like trim and flap motors, lighting, avionics, etc.? I still have a lot to learn about how it all works!
