You can spin it however you like. The logic around the ‘-y’ option requires an extra additional OS call, in this case querying the existence of the file, before it is overwritten.
Even more ... if the option is not set, a console output must be initiated and the user's input must be parsed too. With the option I suggested, this would not be necessary.

When you think of "press", then we are in the GUI world. Most GUI applications I know, ask explicitly before overwriting.
