We plan to unify the generic .inherit_options() functions. The
resulting common function will need to decide whether to force-enable
format probing, force-disable it, or leave it as-is. To make this
decision, it will need to know whether the parent node is a format node
or not (because we never want format probing if the parent is a format
node already (except for the backing chain)).
