NIP-04 is not secure. I don't see any point on releasing something with a complicated double ratchet mechanism using that rudimentary/faulty encryption scheme.

Keychat's messages only use the kind 4 format, with encryption and decryption done using the double ratchet algorithm.

Then it's not NIP-4. You should just use a new kind otherwise current clients will not be able to decrypt it.
