# DEPRECATED! This method of getting user details via track-changes is deprecated
# in the way we lay out our services.
# Instead, web should be responsible for collecting the raw data (user_ids) and
# filling it out with calls to other services. All API calls should create a
# tree-like structure as much as possible, with web as the root.
