What is the purpose of making zones larger than the erase block size of flash? And why are large writes fundamentally unreasonable? I don't see why it should be a fundamental problem for e.g. RocksDB to issue single zone-sized writes (whatever the zone size is because RocksDB needs to cope with it). The write buffer exists as a level in DRAM anyways and increasing write latency will not matter either.
