This might sound insane, but if you modified this into a browser extension that runs locally (with options for one-off or continuous saving for entire browsing sessions) I would probably download it. Personally, I have well over 100TB of personal hard drive space in my home, and I would love to just download entire portions of my browsing history locally for archival reasons (and to truly defeat link rot).
As it is now, I personally wouldn't use it (but it's a cool project, definitely please keep working on this idea!).
