I would say its a much of a deal on mobile as it is on desktop. The problem is how badly Android is doing here compared to Apple. If there were only Android, the problem would be the same for the developers, but they'd accept it in return for the income. Right now, if you can only target one platform, it's a no-brainer against Android. Note that you say "outside of cutting-edge 3D games", but remember that games are a significant part of apps. And cutting-edge on an Android device doesn't have to mean that much. Lastly, consider how console game sales are doing compared to PC game sales. And how developers tend to treat PC game development as a result.
