The ephemerality of iOS applications is the biggest tragedy in software preservation history. So many memories, so much software history, locked away forever on some Apple internal archive server.
I think world might have transitioned past that. Snapchat, Instagram stories all hinge on fact shit moves on. I'd say Slack's best feature on free plan is the fact there isn't way to search all history (potentially wasting you time and giving incorrect outdated information).
