No, my uses of guardians don't rely on this.
Also I'm pretty sure that I'd expect any object added to a guardian to
be returned when that object becomes inaccessible. If cycles can make
this untrue, even when the whole cycle is inaccessible, that's pretty bad.
So I'm happy with your proposal.

Not sure what you mean by this, though. How would this generate an
ordering?
