How does state interact with relations? I.e. if I have a relation to
an object that is deleted, will
it show up in the relation or not? I'm trying to figure out how smart
the code that uses the
model will need to be about this.

(I'll have to think the pending story through a bit more. it's very
important to my use case, including pending relations and the ability
to revert pending items)
