Hi Alexandre, Tablet replicas are not tied to a UUID, so removing or reusing one wouldn't achieve what you want. The main thing missing here is that Kudu doesn't do tablet re-balancing at runtime, so tabletserver5 will get tablets the next time a node dies or if you create new tables.
Obviously that's something we'd like to address but nobody has come around to doing it so far.
