a nearest wins semantics, i.e. if the directly implemented interface is not
marked as provider type it is assumed to be a consumer type (i.e. the default)
and the same for direct super classes which should overwrite the provider role
of any transitive super or interface class?
Update: I just verified with bnd that it is a nearest wins strategy, so a
consumer type (even no annotation, i.e. just the default) wins over a
transitive provider type.

> Project: Sling
> Issue Type: New Feature
> Components: Feature Model Analyser
> Affects Versions: Feature Model Analyser 2.0.0
> Reporter: Konrad Windszus
> Assignee: Konrad Windszus
> Priority: Major
>
> OSGi distinguishes between
> [consumer|https://docs.osgi.org/javadoc/osgi.annotation/7.0.0/org/osgi/annotation/versioning/ConsumerType.html]
> and
> [provider|https://docs.osgi.org/javadoc/osgi.annotation/7.0.0/org/osgi/annotation/versioning/ProviderType.html]
> types (either interfaces or classes).
> Some bundles/features are only supposed to implement/extend consumer types in
> order to be more stable against API changes. There should be a feature model
> analyser enforcing this.
