Yes, and for service providers then you might specify one or two to 
--limit-modules when converging on the set of service provide modules to 
explicit link into a run-time image.

This limits the set of observable modules to `bar` plus the transitive 
closure of `foo`. This will fail immediately if `bar` transitively 
depends on a module that it's in the foo++ set. You might need to work 
through a few examples to convince yourself of course.
