Yeah I don’t think this is gonna get anywhere when the easiest alternative to controlling your account is to just host your own Lemmy instance, and you can do that literally right now with no changes to Lemmy or the protocol.

It’d be nice for ActivityPub to support optional GPG signatures for those that want to have that level of control. That would get you all the identity verification that this new fangled did stuff gets you, with the added bonus of GPG being a reliable, existing, proven technology that people already know how to support.
