it would be nice if kestrel supported a command DRAIN that would refuse SET commands but accept GET commands. would be a great way to clear servers for maintenance.

that would be cool!

latest master support something similar: there is now a STATUS command that can be used to switch the server between up (read/write), read-only, and quiescent states. This can be configured with service discovery via zookeeper, but also works by itself, rejecting the appropriate commands given the current server state.
