This is super interesting. I'm on an android device and have used both amethyst and primal. Does amethyst use the legacy or new DM format? Primal seems pretty active with their development. I'm curious why they wouldn't have updated to the new format. Is there a reason for that, do you know?

Amethyst is one of the pioneers, they do the new DM, but may also support legacy. I am not sure. Primal seems to be focusing on other areas like zaps and content creation tools.
Some people like DMs, some hate :) The flexible nature of nostr allows a lot of types of interactions.
Thanks for sharing your knowledge!
