Hmm. Using this signature kind of enforces that we dispatch based on
which exception *then* then the exception model. I think that's
backwards: since what vectors exist and make sense depends on the
exception model, I think we should ideally be splitting on model
first, then exception type.
Now, a lot of the existing code is exception-then-model and changing
that is a long term project, but I don't think we should lock
ourselves further into doing it the backwards way.

..but making it a QOM object really seems like overkill. In fact
making it a QOM object at least somewhat exposes the internal
structure to the user via QMP, which I really don't think we want to
do.
