Thanks for that info! Didn't realize WARC predated SQLite. Makes me wonder, are there any modern updates that could enhance WARC, or is it only format for archiving?
Yeah, the format really needs an update. For starters, WARC only officially supports HTTP/1.1. Webrecorder has started faking HTTP/1.1 data in WARC files in order to save other versions, but I don't think faking data is great for an archival format, especially if it isn't standardized.
