You'd be surprised. It was the only option for those writing native apps to have a platform that could legally run all of your tooling if you shipped Mac/Windows/Linux.
But given the amount of time they talked about how large a part native apps play into the transitions, an extremely strategically important segment for them.
Additionally, there's the Android/iOS crowd in the same boat, where emulation of non x86 in Android dev is pretty limited (but I can see that being rectified with the newer virtualization extensions).
