Thanks! 
I wrote "I don't understand the description, and this the motivation for adding this operation right now, can you elaborate?", and I think this is still relevant right now. The PR description does not seem to provide enough context to me.
Without understanding why this op is needed, I'm not sure why we're adding it right now. Can we get the end-to-end example? When and where will it be used?
