Double ratchet should not be a column; just because it’s double ratchet doesn’t mean it’s interoperable
Yes, I have indicated as such - see asterisk* and comments.

👆 Keychat directly uses the open-source libsignal (X3DH + double ratchet), while Iris uses secp256k1 to re-implement the idea of the double ratchet.
Nice visualisation. If you break out NIP-17 into "1-to-1 only" and "1-to-1 plus group" it gets even more fragmented.

I think he replied to his own question, there are a few with 1-on-1 only in his reply.
But on his point that it's more work to remove groups than to add groups, I'd argue that NIP 17 groups are like fake groups, nobody can leave or join without breaking the group, so they should be removed for that reason instead, everything to MLS.
