CEV also has another problem that gets in the way of practically implementing it: it isn’t embedded. At least in its current form, CEV doesn’t have a way of accounting for side-effects (either physical or decision-theoretic) of the reflection process. When you have to deal with embeddedness, the distinction between reflection and action breaks down and you don’t end up getting endpoints at all. At best, you can get a heuristic approximation.
