I think this is a bit too vague for a ticket. Robert, could you be more specific or close this?

The coercion model needs to use weakrefs so that parents aren't needlessly referenced when they're discarded. It is nontrivial to see where the weakrefs need to go, and how to do so without slowing the code down.

The ticket is still valid.
