It's just that compaction hasn't occured. TTL works even though GCGS is 0. There's been multiple discussions around this in the past, but we haven't come to a consensus yet though. Some proposals to change compaction strategy, some want to make it customisable. Treating paxos as sub-tables has also come up and the improvements listed in CASSANDRA-13548. TBH we should probably do 13548 and see where that gets us.
