This limitation seems resonable to me too. The main need for the
phased_vars feature is being able to set title, headers, etc, and
those are for the most part determined by the top level ewc, not its
subcomponents. If at some point we realize this is insufficient we can
do the work to remove this limitation, but for now I think it strikes
the best balance between features and ease of implementation.
