Similar to automatic detach, this behavior could be confusing because it can sometimes create a new branch without a user asking it to, especially when the user is still not aware about this feature. In the future, perhaps we could have a config key to disable these safety nets and let 'switch' do automatic detach or dwim again. But that will be opt-in after the user knows what is what. For now give a short option if you want to use it often.
