I definitely miss the cached pages. I found that I was using the feature very frequently. Maybe it's just the relative obscurity of some of my hobbies and interests, but a lot of the information online that shows up in search engines seems to come from old forums. Often times those old forums are no longer around or have migrated to new software (obliterating the old URLs and old posts as well).
When someone asks a thing like this on Lemmy, look up the same thread on Reddit (guaranteed to find it was recently also posted there) and copy-pasta some of the top posts. Guaranteed worthless internet up arrows.
