Seems Google is intending to keep Google Photos, as they have been adding quite a few new features lately.
One is a prompt that has started to pop up for somewhere the back of a head is only visible, and some are seeing a good 80+ percent success rate in recognition.
I'm still only seeing the random automatic cinematic photos, but supposedly there is a manual option rolling out for some. The cinematic effect does really make a photo pop out (the feature uses machine-learning smarts to add simulated depth and motion to static photos, ideally giving them a cinematic feeling).

Google Photos just got better at recognizing people even if their faces aren't visible
