I don't think that's a concern, because we're very unlikely to do it. The
enum values are part of the public API, so changing their names would be a
breaking change.
I don't think this change really makes the code better or more readable,
just different. If we wanted to get rid of the utility isAtLeastOnceProcessing
method in KafkaSpout, I'd rather we just replace the checks with
`kafkaSpoutConfig.getProcessingGuarantee() ==
KafkaSpoutConfig.ProcessingGuarantee.AT_MOST_ONCE`.
