Whether I'm a typical user or a developer does not matter.  This is
unix, and commands are expected to do what they are told.  If you must
do such silly things, at the very least you need to not break scripts
when doing it, which means if stdin is not a tty, don't assume you are
being run by an idiot who needs hand holding and do what you've been
told to.

Scripts and other tools like say, gparted, should not have to figure
out every silly thing you might complain about and add a stupid
- --yes-i-really-meant-it flag to every invocation.
