Major Description
These methods break the abstraction of constructing a composite setup
and should not be used. Since the exported package version of org.apache.jackrabbit.oak.spi.mount is set to 3.0.0 for 1.8-SNAPSHOT and it was 2.2.0 in 1.6.1 it's safe to remove these methods if we do it before a release from the 1.8 stream is cut.
