I don't know.  I did not ask for this, but Juri's remark (that with a 
default configuration the confirmation uses more keystrokes than the 
command itself) makes sense to me.  And setting the user option has a 
global effect, not just on this particular command.  But it's up to the 
maintainers to decide what's the right way to go.
