Actually, it does work, Xah.

If you just try `M-x insert-date' then you won't see that it works.  That's true
also of any other command with a `delete-selection' property.  That has to do
with the region being deactivated when you exit the minibuffer.

To see that it works, bind it to a key and then use the key:
(global-set-key [insert] 'insert-date)
