It seems like there's a missed use case: web archiving. I don't see any mention of WARC as an output format. This could be useful to journalists and academically if they had it.
And while at it, ability to mount the resulting archives at some virtual root in nginx|apache. E.g. serve site-archive.extension at /somepath/site. And standalone simple webserver that can take one or more archives from command line and servers them.
GETOLD /index.html "2026-03-11T10:30:45Z" would be such cool functionality...
