Wait until the Audit of revision 3 finishes: https://github.com/nostr-protocol/nips/pull/746

Looks like we are having some breaking changes from that process.

Amethyst and 0xChat have implemented revision 2 in the new GiftWrapped DM system. And it is much better than NIP-04 for privacy and security. Revision 3 makes it even better.

NIP-04 should be deprecated after this.
