What I'm trying to do with Bookmark Archiver is record user activity to create a puppeteer script while the user is visiting the page, then replay that on a headless browser later and record the session to a WARC. That should cover both dynamically requested and interactive stuff that is otherwise being missed by current archiving methods.

I also plan on saving an x86 VM image of the browser used to make the archive every couple months so that sites can be replayed many decades into the future.
