Currently, youtube-dl marks a youtube video as watched (assuming the flag is on) before starting the download. If the download fails halfway, the video remains marked, but not downloaded. I'd like to request the action of marking as watched to be moved to after the download&merge sucessfully completes. It's a minor annoyance, but it'd save me a bunch of double-checking every time I grab my watch later list.

Current behavior is expected. What you should use is --download-archive.

Except that that flag doesn't change anything about when the video gets marked as watched, so half-downloaded videos still show up as watched in my watch later.

Nothing wrong about that. Half-watched or even only opened in browser videos are similarly marked watched by Youtube itself.
