I wish Apple had an option for 5 years for auto-delete. I don’t need decade old messages, but sometimes 1 year is just a little too short of an auto-delete window. I don’t sit around and look at old messages for fun, it’s moreso about searching for a specific detail about something that was discussed. No different than searching through old emails. And since the current options are basically only “auto-delete everything after one year” or “keep everything for forever”, I go with the latter just in case. Tldr, they need more cleanup options.
