While this is true, one can ask a /dev entry what kind of object it
is.  Since one can do that, one can construct filters that will only
do things for storage objects.

I worry about putting these new event streams at the wrong level
and/or having too many of them making it hard to know what the
appropriate level/event to do something at is.
