> Priority: Minor

> When a leader is elect the leader writes a `LeaderChangeMessage` to the
> replicated log. This message is defined in KIP-595 as:
> ```
> {{{}}
> {{ }}{{"type"}}{{: }}{{"data"}}{{,}}
> {{ }}{{"name"}}{{: }}{{"LeaderChangeMessage"}}{{,}}
> {{ }}{{"validVersions"}}{{: }}{{"0"}}{{,}}
> {{ }}{{"flexibleVersions"}}{{: }}{{"0+"}}{{,}}
> {{ }}{{"fields"}}{{: [}}
> {{ }}{{{}}{{"name"}}{{: }}{{"LeaderId"}}{{, }}{{"type"}}{{:
> }}{{"int32"}}{{, }}{{"versions"}}{{: }}{{"0+"}}{{,}}
> {{ }}{{"about"}}{{: }}{{"The ID of the newly elected leader"}}{{},}}
> {{ }}{{{}}{{"name"}}{{: }}{{"VotedIds"}}{{, }}{{"type"}}{{:
> }}{{"[]int32"}}{{, }}{{"versions"}}{{: }}{{"0+"}}{{,}}
> {{ }}{{"about"}}{{: }}{{"The IDs of the voters who voted for the
> current leader"}}{{},}}
>
> {{ }}{{]}}
> {{}}}
> ```
> The current implementation doesn't include the LeaderId in the set of
> VoterIds. In the protocol it is guarantee that the leader must have voted for
> itself.
