Review Comment:
   This used to happen when inMemoryVoters.isEmpty() is true too. Is it 
intentional to omit it now?

Review Comment:
   Claude found the following. Is that a real issue?
   
   Routine UpdateVoter traffic can block admin voter changes
   UpdateVoter is periodic at fetchTimeoutMs (default 2000 ms, 
FollowerState.java:157-161), has no backoff on failure (the timer resets when 
the request is sent, KafkaRaftClient.java:3352; only NONE/UNSUPPORTED_VERSION 
set hasUpdatedLeader, :2596-2602), and now holds the exclusive slot for an 
API_VERSIONS round trip bounded by the request timeout (also 2000 ms). 
isOperationPending (ChangeVoterHandlerState.java:318) now includes the update 
state, so AddVoter/RemoveVoter get REQUEST_TIMED_OUT.
   
   A voter advertising an endpoint the leader can't reach retries every 2 s 
forever with a near-100% duty cycle on the slot — and the operator's remedy 
(remove-controller) is exactly what's blocked. Both timers are fixed with no 
jitter, so they can beat against each other.
