I wanted to make a site/personal list of “approved” videos (for kids for example) and the expectation would be a way to detect if the video has been altered since it was “approved” - like mark a dirty bit until it can be reviewed again. I haven’t actually gone deep enough in metadata or API or anything to see if that data is available (last modified or a hash of some sort) But the fact it doesn’t show this on the frontend makes me wonder if that’s even a detail I could get.
