ComputedFolder in the cloudbees-folder plugin defines a folder whose children are computed by some process. Currently it is used only for organization folders, but it would be natural to integrate it with the Job DSL plugin: the definition of the folder would include the DSL script (or a link to its location), and the script would have some way of expressing the enumeration of child items. Folder recomputation would rerun the script, on demand or on a schedule. Child items would be view-only.
