Done.

It would actually be hard to prevent. throw() would most easily be
implemented under RFC 63 as a core function and a method of the Exception
class; a core function for handling the
throw $exception
case, and a method for handling the
throw Exception::IO(args)
case (using indirect object syntax). If that were so, even without the
ignore() function, I could just say
sub Exception::IO::throw { 'do nothing' }
and kill it that way.
I am open to suggestions on whether we should make it impossible for
someone that determined to shoot themselves in the foot to do so. My
feeling is that someone smart may have a good reason for doing it (in their
own code, not in a module given to others), and someone dumb deserves what
they get for doing something so blatantly stupid.
