- [ ] Yes I am willing to submit a PR!

Start by tracing how the coordinator handles the decommissioning server status, using the coordinator-side decommission operation described in the issue as the entry point. Reproduce the reported behavior on master and identify the missing reaction; done means the coordinator correctly responds when a server is decommissioned.
