I can't speak for what Apple's done, but it seems natural to me like
#3.  "state data" isn't a great term for this; they're notifications of
things, as they happen.  So it seems to me that you'd want something
like (forgive my syntax, don't take this literally!  I don't speak MI
at the moment):

=breakpoint-changed,[bpnum="1",state="disabled"]
=thread-changed,[thread="2"]
