The above behavior exists because people who have been exposed to Git
think this is the command to switch branches. So they would get the

..and not realized they hadn't switched branches (because Git taught
them not to bother reading output) and then be confused/upset/blame the
tool when they had two heads.

So no, we can't switch this back.
