AbstractFolder does not provide a hook for plugins to contribute a static view configuration, rather it stores the mutable view configuration.

Some folder sub-types (typically based off of ComputedFolder, but this is probably more general) have a requirement for the views to be specified based on programmatic criteria where synchronizing the configuration with the mutable list will result in unnecessary configuration file changes.

In this regard it makes sense to refactor the view configuration of an AbstractFolder into an extension point that can be replaced by concrete subclasses.
