Yeah.  ISTM the real bottom line here is that we have only a weak grasp
on how these features will end up being used; or for that matter what
the common error scenarios will be.  I think that for the time being
we should err on the side of being permissive.  We can tighten things
up and add more nanny-ism in the warnings later on, when we have
more field experience.
