Ah okay! I can see the need for this. This is a large part of why the States machinery exists, but I see your point about it being error-prone to remember to tag and then despawn everything.
I'll chew on solutions here: we might be able to get away with a nice well-documented convention in user-space code, or we may need to add a small extension to the internals to make this more robust.
