Is this not the case on El Capitan already?
See the below screenshot of my iCloud drive with some random files in it I just took on my 10.11.5:
Some files (bigger, older) move to 'cloud' and do not reside on my Mac until I try to open them. I have got over well over 25% of free storage on my Mac.
How is this macOS Sierra's feature any different to what El Capitan already does? (except by making it explicit to users this time)
