@jupiter_rowland @GossiTheDog @mikedev @joho That's right, it is hard to introduce nomadic identity without disturbing existing users. All upgrade paths have serious disadvantages. The one I am currently exploring requires splitting the codebase into two components, server and client.
To be honest, I don't think Mastodon will ever support nomadic identity. Even if we put philosophical questions aside, and consider only the technical complexity, going nomadic is an enormous task that will require many year of hard work.
They can support remote nomadic accounts with less effort, though
