The best you've got is "essentially off" but that wording is such because even with everything disabled there are still edge cases where their security will enforce a JS challenge or CAPTCHA.
I don't really know how you resolve that absent just like... putting everything behind logins, though.
So give me xxx minute old stale cached version. I'm fine with that.
Not all sites are configured to do this. Some pages are expensive to render and have no cache layer.
They solve the DDOS issue by requiring JS captchas (which fundamentally breaks the way the internet should work), rather then serving a cache of the page to reduce load on the real host.
Requiring JS doesn't disambiguate between well behaved automated (or headless. I used a custom proxy for a lot of my content browsing) user agents and malicious users, it breaks /all/ of them.
Like, I get the need for some protective mechanisms for interactive content/posting/etc, but there should be zero cases where a simple HTTP 200 GET requires javascript/client side crap. If they serve me a slightly stale version of the remote resource (5 minutes/whatnot) that's fine.
They've effectively just turned into a google protection racket. Small/special purpose search/archive tools are just stonewalled.
