Michael Dürig commented on JCR-1797:
------------------------------------

Specifically I'd like to be able to return items for getItemInfos(sessionInfo, nodeId) which are not in the sub tree rooted at nodeId.

This is useful in the case where an underlying data store returns such items anyway. For example an underlying data store might always return the parent and all grand-parents of a requested item and probably even some of its siblings (i.e. MS Sharepoint). 
While traversing a repository from the root node to the leaves, there wont be any gain. However, there is quite some impact on random access. For example when iterating over the result set from a search.
