I'm with you on this point nostr:npub1clk6vc9xhjp8q5cws262wuf2eh4zuvwupft03hy4ttqqnm7e0jrq3upup9.
You can't unsay something. Scars of the past can be visible and be painful, but we still deal with them. It takes maturity for both sides to acknowledge where you were previously while also acknowledging who you are now.
However, I do understand the desire for a retraction+delete, and the current social implications for statements being on one's permanent record.
Socially, I'd hope that a system robust against deletion would encourage us all to be more compassionate towards our snapshotted selves while discouraging canceling over previous actions.
