Yeah, I agree. That’s why my last attempt at key rotation wasn’t about key rotation at all, but about identity continuation. And I think not everyone, but some people might use it, specially entities or "high value" accounts. As I see it they would work more like a kind of change.org campaign. "Hey, this is my new key, there you have some proofs (wot voting, secret revelation, any other proof) that this is me and not an impersonator"
