Additional context

How will you/everyone benefit from this feature?

I think there are certain advantage to this:

1. Privacy, since the history is deleted it is impossible for others to obtain a long term watch pattern of a person.
2. Save space, the watch history (including what part of the video has been watched) can gets really large after years of use
3. It does not hurt convenience, I personally never found myself in need of finding videos that I watched weeks ago. But I do sometimes need to use history to find what is the last video I have watched.
