We are using such chains in Power, Pipeline and Telecom groups. It works
power=transformer + transformer=distribution + voltage:primary=20000 +
man_made=street_cabinet + street_cabinet=telecom + telecom=exchange +
telecom:medium=copper + operator=Orange

This dosn't include the redundancy in namespaces' prefixes which is worse.
