I would vote for 3) as 1) would not work as the CachingOptimizer will try to query from the cache.
In addition, we could have is_set_in_optimize and the CachingOptimizer checks is_set_in_optimizer || is_set_by_optimizer.

It might actually be easier just to have this slight work-around for callback attributes. We don't have many, and it's simpler than defining a new check with all the correct plumbing. If we have many more attributes, we can revisit this.
