Most people wouldn't know how, or even bother (like you said, the desktop is just a single tap/swipe away) and I bet that's what Microsoft is counting on. Although I wouldn't be surprised if Microsoft added the option themselves due to overwhelming complaints. Remember how the free version of Visual Studio 2012 wouldn't allow desktop apps to be created (only Metro apps) until there was a huge outcry on social media? It's not too late for them to change their mind.
