Sure, this counts as a compelling usecase. Maybe your API just lets users list Items chronologically since that makes sense for your site, but someone else wants to get Items by location.
Many times, the only way to do what you want with data is to use the API to get everything, then transform it locally. This is obviously really inefficient (and sometimes impossible).
