Saving logs is gross, chats should be ephemeral. In any case there's HistServ and IRCv3 /chathistory nowadays, so if you really want it you can have it.

That all the minute garbage everyone posts is preserved forever in an unfiltered state I think is a root cause of the mental degradation that results from using Discord: kids don't have anywhere to 'post into the void' anymore. Preserving past events and relationships through oral history as opposed to a big monolithic search engine entails a far more human element to IRC.
