Unlisted visibility doesn't change the fact that my own replies to other people's deleted posts will still appear on my profile weeks/months/years later, out of context.
Other people's recent local feeds etc. are not my concern here, and most of the time I come across deleted posts much later because people use the auto-delete feature for their own posts in 1 month, 6 months etc. increments.
A timeframe that I doubt very many people try to scroll through.
