Defer isn't allowed because you don't want ordinary users to be able to
use it. At least, that's my judgement. Fail, I guess, is marginal. It
probably does no harm for ordinary users to be able to use it, as indeed
:blackhole: does no harm.
But it's too late to make incompatible changes now. I promised. So is it
worth actually making any change at all?
