Boot to Desktop: Bad for Microsoft?

There are rumours that a "Boot to Desktop" option will be enabled in Win 8.1. But isn't that bad for Microsoft? People will bypass the Metro start screen and its importance and usage will reduce. This means lesser visibility and access for Metro apps. This would lead to reduced developer interest in building Metro apps. This would affect Microsoft's tablet and unified phone strategy as without good Metro apps the Surface tablets and other Win 8/RT tablets would not take off. So why would Microsoft do this?

Ofcourse many users have been complaining about the Metro start screen but there is no evidence that it is a majority and even so people always get used to UI changes over time. Metro was supposed to be Microsoft's bet for the future of Windows computing. Such a drastic change would indicate a backtracking and lesser commitment which will again affect developer interest in the platform.
