Done. nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z Here’s the fix for Amethyst to add write support for NIP-10 deprecated positional tags in text notes to maximize backwards compatibility.
https://github.com/vitorpamplona/amethyst/pull/737

It’s a much larger lift to add support for the recommended approach of NIP-10 event tag markers on the Damus side, though, so I’ll leave that alone for now.
