Handling deleted videos

Hi! I did look at the documentation, apologies if this is documented somewhere I missed, but I think there are probably feature requests in what I'm about to discuss anyway. How does yark handle video removal from a channel or playlist? There are channels I archive with yark for which I absolutely do NOT want to remove videos, ever. I have extra backups so I know at least the actual video files are safe, but it would be nice to have a "no delete" option - maybe that would mark the videos as having been deleted when serving the site, but leaving them there.
