(uniquely) does not make -Werror abort the compilation? That seems a bit
irregular... But perhaps you have something in mind.
Perhaps we should have separate control for two different classes of
orphan warnings:
* those where the class and all the types are in other packages (and thus
you may not be able to easily avoid the instance, e.g. if everything is in
the base package).
* the rest
