@homegrown @gbargoud @TimothyRoes thank you for your writing on Fedi.tips, very nice!
One caveat, which you mention in the post but might be worth calling out: you can't migrate an account's posts currently, and that IMHO amounts to a "no" answer to "can I move my account". Mastodon has redefined moves to only be about followers and followed but I believe that doesn't quite make sense for general users and we should not normalize this definition.
